A. Highlights of the previous report presented in Nov 2016.

Though the project officially started in Jan 2016, it really took off from the month of May 2016 when the Kick-off meeting took place in IISc, Bangalore. A summary of the report done for the next five months (officially 9 months) was presented during Nov 2016 at Varanasi. Here we present the highlights of the report presented during Nov 2016. i) The main part of the report was about the Kick-off meeting, which set up the organization of the

network. This included the setting up of the collaboration webpage, formation of the working groups, formation of the steering committee, methodology of the visits and other organization details. These were required for the day to day functioning of the network.

ii) Scientifically, the formation of the working groups and identification of the discussion leaders associated with them helped to identify specific research areas that would be targeted by the network. This not only brought experts from both the Indian and French sides together with common research goals, but also provided them with a platform to efficiently collaborate with each other.

iii) There were more than 3 publications in this short span with explicit acknowledgments to CEFIPRA/Indo-French collaboration and four publications within the framework but started before the formal launch of this network.

iv) Within the short span, 2 of the 15 allotted visits were utilized from France to India, where as 0 out of 20 were utilized from India to France. Of the allotted 10L for the conference budget, all the 10L was utilized and further an equal amount was matched up from other resources.

v) It was noticed that the driving force of this network collaboration was the young faculty, students and post-docs; who actively sought collaborations from either side.

B. Main highlights of this report The present report covers the subsequent 11 months from Nov 2016 to Sep 2017. During this period, the organization of the network has really stabilized and many other working groups have also started on collaborations. At this point almost all the Indian as well as French nodes are actively involved in collaborations which are at various stages. We can confidently say that the network is it in its most active period and we hope that this momentum will carry forward for the next coming years. We summarize the main highlights below with the details described in Part-2 of the report. i) Excellent quality research has emerged during the past few months because of the collaboration,

some of which could have long-standing implications on the field. One such example is the set of newly proposed techniques for discovering new particles at the LHC.

ii) The total number of publications during this period is thirteen iii) The total number of visits from France to India have been 3 out of remaining 13 with one more

planned in the later part of year 2017. Four visits out of 20 from India to France have taken place during this period. One more visit from India to France is planned in the coming month.

iv) Organizationally, it has been noticed that the students are paid a lower per-diem of Euros 50 per day which also is intended to cover their accommodation cost. Given the higher accommodation costs, this rate of Euros 50 per-diem was grossly insufficient to support the student visits. A representation was put forward to CEFIPRA’s director and the Scientific council for the revision of the student per-diem to 100 Euros per day. The CEFIPRA council approved this revision so that the later student visits are better supported with the new rates.

v) Almost all the working groups are now active and all the nodes are actively collaborating with each other. A nodal chart is presented in the Part-2 of the report.

vi) Another workshop is being planned in IISER, Pune in the last week of Feb 2018. The workshop would have a similar format as the Kick-off conference and we expect that it would reinforce the already formed collaborations and set a stage for the new ones.

vii) Training of Students and Post-docs: There were at least two occasions when the students in India could get trained by the French experts. Prof. Boudjema and Prof. Cacciapaglia gave lectures to students on their topics of expertise detailed below.

viii) Several new members have shown interest to join the collaboration. Some students and post-docs have left their home institutions and have joined prestigious laboratories around the World (Japan, Taiwan, France, Italy,..). New students and post-docs would like to join the network and take part in the collaborations.

II WORK REPORT BriefreportoftheworkdoneontheprojectfortheperiodNov2016toSept2017coveringworkdoneinbothFranceandIndia While the funding has started officially from January 22, 2016 the actual collaborations have started taking place after the kick off meeting held during May 2-5, 2016 at IISc, Bangalore. Before commencing the actual report on the work done, here we revisit the summary of our project and its objectives. These are already presented in the proposal as well as in the previous report.

A. Summary of the project We proposed to have a CEFIPRA sponsored NETWORK of Institutes from India and France focussing on all areas of High Energy Physics (HEP) including theory, phenomenology and experiments. We would like to call it INFRE-HEPNET or CEFIPRA-HEPNET. At a time when the LHC is in full swing and experiments in astrophysics and cosmology are providing admirable data we would like to consolidate our efforts in this area based on a long and successful tradition of collaborations between India and France in this field. The two main research themes along which this project has been based are

a) Physics of the Standard Model (SM) and beyond (BSM) b) QCD/Quark Gluon Plasma

1. Original objectives

We repeat the non-academic objectives listed above in Section-I here. a) First, we aim to increase collaboration between India and France in High Energy Physics. b) To conduct collaborative meetings between the French and Indian scientists and foster strong

partnerships between Indian and French Scientific counterparts is another target. c) One of the objectives is to increase interactions between theorists and experimentalists of both

the countries. A unique feature of this Network collaboration is that both experimentalists and theorists are members.

d) To collaborate and conduct research at the highest level in the focussed areas of BSM physics and QGP is paramount to the success of the project.

e) Training of manpower, students and postdocs, is an important part of the Network.

While the above form broad objectives, in terms of pure research programme it was proposed to have the following four working groups within the two broad streams of BSM Physics and QGP.

a) WP1: Higgs in the SM and beyond b) WP2: Beyond the SM physics at the LHC c) WP3: Dark matter and the LHC d) WP4: QGP

Within each of these proposed working groups, several objectives were listed in the original proposal. For example, for WP2: Beyond the SM physics at the LHC, the objectives are listed as below

a) General and model independent approaches b) SUSY and SUSY-based analyses c) Extra dimensions d) Vector Quarks

A summary of all the proposed objectives and their network node distribution is presented in the Table 2.1 table below. This year the results have started pouring in from various working groups and various nodes about the research collaborations that are taking place. We summarize them below.

2. Report on the project work done

a) Node-wise breakup of the current research collaborations Here is the pictorial representation of the current research collaborations between various nodes. All the

nodes are now actively engaged in research collaborations, many of which have already been published or in the process of publication.

The QGP group has only one link as the groups were concentrated only at Saclay in Paris and TIFR/Mumbai-IISER/Pune node.

Work on BSM and New Physics involves a larger community which is also reflected by the number of collaborations (and visists) in our Network and the vast array of topics covered in our project.

b) Results of the collaborations and visits Herewelistthesummaryofvisitsconductedbyvariousindividualsandtheirscientificoutcomes.

i) Susan Shotkin Gascon-Shotkin, November 13 to 20, 2016 to TIFR One major result completed which would not have been possible without the contribution of members of the SINP-Kolkata CMS group, collaborating with IPN Lyon (S. Gascon-Shotkin et al.) and IHEP-Beijing (G. Chen et al) CMS groups: Public preliminary result of the search for a 2nd Higgs boson in the diphoton decay channel in CMS using both the Run 1 (8 TeV, 2012) and Run 2 ( 13 TeV,2016) datasets, made public on Sept. 22 2017. Limits set on the product of the cross section with branching ratio in the range 70 GeV<m_gamma gamma<110 GeV. One excess at m=95.3 GeV having a statistical significance of 2.8 sigma. There is now a public note on this result, entitled Search for new resonances in the diphoton final state in the mass range between 70 and 110 GeV in pp collisions at √s= 8 and 13 TeV by the the CMS Collaboration, September 2017 In this note the results of a search for a new resonance decaying into two photons are presented for a diphoton invariant mass in the range between 70 and 110 GeV. The analysis uses the entire dataset collected by the CMS experiment in proton-proton collisions during the 2012 and 2016 LHC running periods. The data samples correspond to integrated luminosities of 19.7 fb-1at √s= 8 TeV and 35.9 fb-1at √s= 13 TeV. The expected and observed 95% confidence level upper limits on the product of the cross section times branching ratio into two photons are presented. No significant excess with respect to the expected limits is observed. The observed upper limit for the 2012 (2016) dataset ranges from approximately 133 (161) fb at the mass hypothesis of 91.1 (89.9) GeV to 31 (26) fb at a mass of 102.8 (103.0) GeV. The statistical combination of the results from the analysis of the two datasets in the mass range between 80 and 110 GeV yields a minimum (maximum) observed upper limit on the production cross section times branching ratio normalized to the Standard Model-like expectation of approximately 0.17 (1.15) corresponding to a mass hypothesis of 103.0 (90.0) GeV.

iii) Charanjit Kaur Khosa, June 2 to 17, 2017 to LAPTh, Annecy During this visist work started on a project related to the CP nature of the dark matter mediator in single top+ dark matter processes in the simplified dark matter models, in collaboration with Prof. Genevieve Belanger and Prof. Rohini Godbole. We have already estimated the relevant cross-sections in this framework and verified the various polarization sensitive distributions with the existing results. Our plan is to probe the CP nature of the mediator considering these processes using the polarization and cross-section information. This work is in progress.

iv) Aldo Deandrea, February 28 to March 4, 2017 to TIFR, Mumbai The precise measure of the Higgs mass is an important quantity to discriminate a part of the parameter space of supersymmetric models, together with the other Higgs boson properties and direct searches of new particles. The project focuses on models beyond the Standard Model containing an extended Higgs structure, in particular Higgs triplets respecting the custodial symmetry and the interplay with extra dimensional supersymmetric models. This allows to build models in which the Higgs mass at 125 GeV can be natural, meaning that no strong fine tuning of the parameters is needed to obtain it. We both focus on the phenomenological implications of such models and on model building. The collaboration started in 2016 with the kick-of meeting in Bangalore and the visit of A.Iyer and K.Sridhar in Lyon. We plan to continue it with my visit in Mumbai and a larger discussion with the other collaborators in Delhi on the occasion of a conference in the second part of my visit.

v) Giacomo Cacciapaglia, March 12 to 16, 2017 to Delhi University Study of the phenomenology of vector-like quarks in configurations where more than one state is present (work in progress with Prof. Gaur). Initiate a new project on the properties of the Higgs boson, in particular in model with extra dimensions. A collaboration with Prof. Gaur, connected with an exchange programme with common collaborators in Japan, has been in place since 2009 leading to 4 common publications so far. Giacomo gave also a series of lectures in India on the anatomy of composite dynamics including Higgs and dark matter phenomenology.

vi) Jayita Lahiri, September 9 to 29, 2016 to LPSC, Grenoble, France There are two projects which I am working on with my collaborators under CEFIPRA.

a. Aldo Deandrea, Sabine Kraml, Jayita Lahiri, Solene Le Corre -We study the current status of two Higgs doublet models of types I and II in the alignment limit. Special attention is given to the impact of the latest LHC Run 2 Higgs measurements. A paper draft exists and should be submitted to the arXiv soon.

b. Rohini Godbole, Monoranjan Guchait, Charanjit Kaur, Jayita Lahiri, Seema Sharma, Aravind H. Vijay - Searching for observables involving top polarization and understanding jet-substructure techniques in case of boosted top quark produced in decay of heavy resonance at LHC and decaying hadronically to produce highly collimated jets. We would also focus on improving the top-tagging efficiency in the high pT regime mentioned above.

c. There has not been any publication yet, but we are hoping to publish the ongoing projects very soon.

vii) Juhi Datta, May 2017 to LPSC, Grenoble, France SModelS is a tool developed by Prof. Kraml and her collaborators in Grenoble, Vienna and Sao Paolo, which enables interpretation of supersymmetric model results from the LHC in the context of BSM physics scenarios. Specifically, it decomposes BSM scenarios in terms of simplified model topologies and compares them against the LHC results. Towards the beginning of my visit, I learned the basic concepts and working of SModelS besides reviewing the current status of the Moriond results from CMS analyses of the 13 TeV run data of LHC and their usability in terms of information provided from the experiments. I also attended the “SModelS Fest V’, a 10 day discussion meeting of the SModelS developer group held at LPSC during this period. I also went on to learn the procedure for implementation and validation of new analyses (for multiple jets and missing energy and multiple leptons and missing energy) which serve to extend the existing database of SModelS and are being incorporated in the SModelS database to compare new physics models against LHC results. We also implemented and validated several of the new results from CMS of the 13 TeV Run data of LHC, presented at Moriond Conference (March 2017). New topologies were included in SModelS as neccessary. An updated SModelS database including these results will be publicly released as soon as possible.

viii) Visit by Siddharh Dwivedi, HRI to LAPTh, Oct. 2016

S. Dwivedi gave a talk at LAPTh, Annecy, on his work on anomalous Higgs couplings, especially CP-violating HWW/HZZ couplings and their signatures at the Large Hadron Collider (LHC). During this visit, they studied the helicity amplitudes of associated VH productions in this context. They verified that any CP-violating coupling would in the process produce transversely polarised gauge bosons in the process, while CP-conserving couplings would result in logitudinally polarised bosons.

ix) Jean-Yves Ollitrault, (November 20 to December 3, 2016 to TIFR, Mumbai) and Rajeev Bhalerao, (June 5 to July 8, 2017 to Saclay, Paris) Work submitted for publication: Effects of initial-state dynamics on collective flow within a coupled transport and viscous hydrodynamic approach We evaluate the effects of preequilibrium dynamics on observables in ultrarelativistic heavy-ion collisions. We simulate the initial nonequilibrium phase within A MultiPhase Transport (AMPT) model, while the subsequent near-equilibrium evolution is modeled using (2+1)-dimensional relativistic viscous hydrodynamics. We match the two stages of evolution carefully by calculating the full energy-momentum tensor from AMPT and using it as input for the hydrodynamic evolution. Unlike some earlier works based on classical gluon dynamics, we do not find the initial shear viscous tensor to be large. With a shear viscosity to entropy density ratio of 0.12, our model

describes quantitatively a large set of experimental data on Pb+Pb collisions at the Large Hadron Collider (LHC) over a wide range of centrality: differential anisotropic flow v_n(p_T) ~(n=2-6), event-plane correlations, correlation between v_2 and v_3, and cumulant ratio v_2\{4\}/v_2\{2\}. Chandrodoy Chattopadhyay (TIFR), Rajeev S. Bhalerao (IISER Pune), Jean-Yves Ollitrault (IPhT, Saclay), Subrata Pal (TIFR), e-Print: arXiv:1710.03050 [nucl-th] Work in progress: Symmetric cumulants SC{m,n} which measure the correlations between event-by-event fluctuations of the magnitudes of azimuthal flows in harmonics m and n, are relatively new observables for experiments involving ultrarelativistic heavy-ion collisions. They provide a robust measure of the collectivity unbiased by (spurious) nonflow effects and thus provide new constraints on the unknown initial state of the collision. As the final-state flow pattern is the collective hydrodynamic response to the initial conditions fluctuating event by event, it is of interest to study similar correlations between magnitudes of the initial-state spatial eccentricities in different harmonics. During this visit we have initiated a study of these initial-state symmetric cumulants both analytically and numerically. Analytic expressions were obtained to order 1/N^2 where N is the number of participants. Rajeev S. Bhalerao, Jean-Paul Blaizot, Giuliano Giacalone, Jean-Yves Ollitrault

x) Shankha Banerjee, November 15 to 30, 2016 to IISc, Bangalore Working on a detailed phenomenological study revisiting various Standard Model (SM) channels for the non-resonant di-Higgs production. We are optimising each of these channels and trying to estimate the combined significance for the non-resonant di-Higgs production at the High Luminosity LHC (HL-LHC). Besides, we are also studying some resonance di-Higgs scenarios with the same decay modes as above. Finally, we are also considering certain beyond the SM (BSM) processes which might lead to same/similar final states as for the non-resonant di-Higgs scenario. Collaborators: Amit Adhikary, Biplob Bhattacherjee, Rahool Kumar Barman and Saurabh Niyogi Status: Almost completed. Should be out soon.

xi) Shankha Banerjee, December 02 to 20, 2016 to SINP, Kolkata A discussion on CP-violating dimension 6 operators with Professor Bhattacharyya during my visit in Kolkata. More work needs to be done from my side. Collaborative work under progress (without any visits on my part). (a) Work with Dr. Amit Chakraborty, Professor Fawzi Boudjema and Dr. Bryan Zaldivar. The inception of this work happened when Dr. Chakraborty was visiting(as a part of the Indo-French initiative). Progress report: We are working on studying the prospects of deciphering light scalars (of the order of 10-30 GeV) by counting the number of soft tracks emitted from such scalars. We are studying it in the context of a modified monojet-like analysis. A proper merging technique for such processes has been recently consolidated on our part. More work needs to be done. Status: Progressing. Should tentatively be finished early next year.

xiii) Fawzi Boudjema , March 30 to April 4, 2017 to HRI Allahabad The main purpose of the visit is to introduce students/post-doctoral fellows and faculty to the subject of radiative corrections especially for the electroweak theory and models of new physics. This is a technical but very important topic where there is no expertise in India. I gave a series of 5 lectures (about 9h total) Topic: Electroweak radiative corrections— techniques and applications About 23 students and faculty attended the lectures. I have also made available most of the material and allowed the audience to contact me in case of a problem in going through the course. The lectures can be found here https://lapp-owncloud.in2p3.fr/index.php/s/wYQdgULojGzzi2V Collaboration with a PhD student Nabarun Chakrabarty on the renormalisation of the Inert Doublet Model (IDM) in view of calculating the relic density of dark matter in this model. This work was initiated by S. Banerjee (LAPTh) and Nabarun and is now being generalised for a full renormalisation of the model. Very good progress was made during the visit of Nabarun in July 2017 (see below).

xiv) Fawzi Boudjema, April 9 to 12, 2017 to CHEP, IISc, Bangalore 1) One aim of the visit was to work with Sudhir Vempati, the Indian coordinator of the CEFIPRA network, on a letter to CEFIPRA to set stricter rules for a smoother working of the Network as well as setting priorities and giving clear scientific reorientation for the project. 2) I benefited from my stay at CTS to start a project with Biblop Bhattacherjee on the idea of long-lived particles at the LHC. This project was further developed when Biblop visited LAPTh in May/June. A new paper has appeared which received a very good exposure. The paper is now under review. I, here, give the abstract Novel signatures for long-lived particles at the LHC Shankha Banerjee, Geneviève Bélanger (Annecy, LAPTh), Biplob Bhattacherjee (Bangalore, Indian Inst. Sci.), Fawzi Boudjema (Annecy, LAPTh), Rohini M. Godbole (Bangalore, Indian Inst. Sci.), Swagata Mukherjee (RWTH Aachen U.). Jun 22, 2017. 7 pp. LAPTh-021-17 e-Print: arXiv:1706.07407 [hep-ph]

In the context of searches for long-lived particles (LLP), we have shown, using several benchmarks, that objects which emerge from a secondary vertex due to the decay of an LLP at the TeV scale, are often at large angular separations with respect to the direction of the parent LLP and a fraction of the decay products can even go in the backward direction. These will give rise to striking signatures in the detectors at the LHC. It is worthwhile to perform dedicated searches for these signatures, and we suggest some variables that could be used to identify such unconventional signatures and reduce backgrounds coming from instrumental noise and cosmic rays.

xv) Abhishek Iyer, October 4 to 15, 2016 to IPNL, Lyon Vector like quarks are proposed by many extensions of the SM. Consequently there are dedicated searches for these massive states mainly through their direct production modes. However this particular channel can limit the mass range which can be probed at the LHC. In the work with Prof. Deandrea, we propose a strategy to significantly enhance the reach of these states. This is rendered possible by the observation that most models which predict the presence of VLQ are also characterized by the presence heavy coloured bosons (B). We assume that these bosons are much heavier that the VLQ thereby leading to the following process: pp> B > VLQ + t, where the VLQ are produced from these coloured bosons along with a top. Fairly large cross sections even for significantly heavy B enables us to push the reach of VLQ as compared to the direct production modes. Further we adapt a universal search analysis wherein our strategy can be applied to any possible decay mode of VLQ. This work has been submitted to Arxiv and is available on the following link: https://arxiv.org/abs/1710.01515 This work is currently under review at PLB

xvi) The IDM model and its renormalisation. Visit of Nabarun Chakrabarty (HRI) to LAPTh Annecy � While the quest for physics beyond the Standard Model (SM) is on atthe LHC, no conclusive evidence any such additional dynamics has emerged so far. However, a careful measurement of the SM couplings, in particular, the Higgs couplings, can help us pin down possible new physics effects that can modify such couplings in a radiative manner. This prompted us to investigate the impact of electroweak (EW) radiative corrections on dark matter (DM) phenomenology. And, for this purpose, the inert doublet model (IDM) was chosen as a prototype scenario. In addition to the SM fields, the IDM features an extra SU(2) _L scalar doublet that does not pick up a vacuum expectation value (VEV) owing to a Z 2 symmetry. The CP -even scalar (H) of the inert doublet was taken as the DM candidate. One-loop EW corrections to the HHh interaction were computed, and the percentage change in the thermal relic density and direct detection rates were estimated, with respect to the corresponding tree level values. It was seen that though the tree-level H − H − h coupling is a prima facie free parameter, the percentage change from loop effects can be large. These results can be found in Shankha Banerjee and Nabarun Chakrabarty, arXiv:1612.01973. � We have initiated a full renormalisation of the IDM. The goal is to compute EW radiative correc- tions to all possible couplings in the given scenario. Upon completion of the renormalisation, for instance, one would be able to study radiatively corrected coannihilation rates, something that was not a part of the previous study. The renormalisation is being implemented in the framework of the tools LANHEP, FormCalc and LoopTools. It has emerged in course of this study that the renormalisation scheme is not unique. We have already implemented the coun- terterms in the On-Shell (OS) scheme and what remains is a proper comparison among different schemes, say, between OS and MS. The collaborators on this project are Nabarun Chakrabarty Fawzi Boudjema, Shankha Banerjee and Guillaume Chalons.

xvii) Jacky Kumar, TIFR, Mumbai, September 15 to October 8, 2017 to LAPTh, Annecy Fawzi Boudjema and Jacky Kumar are working on the Next-to-minimal supersymmetric standard model(NMSSM). In a certain region of NMSSM parameters space its light pseudoscalar can decay to diphotons with an enhanced branching ratio. This happens if the pseudoscalar is mostly singlet like and such particle can be produced via decays of neutralino in chargino-neutralino associated production (Phys.Rev. D95 (2017)). In this project we are examining the other features of such a parameter space of NMSSM. The aim would be to figure out some interesting accompanying channels and use them to reconstruct, if possible, the NMSSM parameters or make future projections. In a related work, we are checking if the channel HSM → A1A1 → γγ γγ can be used to probe the heavy Higgsino (∼ 1T eV ). The ideas is related to the fact that for a singlet A1, the decay A1 → γγ occurs via Higgsino loop. Now, if this mode is found to be enhanced even for the heavier Higgsino, then this might be used as an indirect probe of the heavier Higgsino in NMSSM.

Other projects not necessarily the result of visits but exchanges HRI-LAPTh Current data (LHC direct searches, Higgs mass, dark matter-related bounds) severely affect the constrained minimal SUSY standard model (CMSSM) with neutralinos as dark matter candidates. But the evidence for neutrino masses coming from oscillations requires extending the SM with at least right-handed neutrinos with a Dirac mass term. In turn, this implies extending the CMSSM with right-handed sneutrino superpartners, a scenario we dub ν~CMSSM. These additional states constitute alternative dark matter candidates of the superWIMP type, produced via the decay of the long-lived next-to-lightest SUSY particle (NLSP). In this project, a study took place for the case where the NLSP is a τ~: despite the modest extension with respect to the CMSSM this scenario has the distinctive signatures of heavy, stable charged particles. After taking into account the role played by neutrino mass bounds and the specific cosmological bounds from the big bang nucleosynthesis in selecting the viable parameter space, a study was carried out on discovery prospects for this model at the future runs of the LHC. It was shown that it is possible to probe τ~ masses up to 600 GeV at the 14 TeV LHC with L=1100 fb−1 when one considers a pair production of staus with two or more hard jets through all SUSY processes. One could also see the complementary discovery prospects from a direct τ~ pair production, as well as at the new experiment MoEDAL. The results mentioned above can be found in the publication Shankha Banerjee, Geneviève Bélanger, Biswarup Mukhopadhyaya, Pasquale D. Serpico, JHEP 1607 (2016) 095. Some follow-up studies on the lepton flavour structure of the above scenario is currently in progress.

3. Budgetary Matters and Issues

a) Visits There have been two calls for the visits under the collaboration, one during Dec-Jan 2017 andanother during July 2017. The steering committeemet andmade decisions according tomerit ofeachapplication for a visit. Theacceptance levelwas veryhigh.Here is listofpeoplewhosevisitshavebeenapprovedeitherunderLIAorunderCEFIPRA.

b) Students per-diem UnderCEFIPRArulesstudentstravelingfromIndiatoFrancearegivenaper-diemofEuro50perday.Thisisexpectedtocoverboththeaccommodationcostsaswellaslivingexpenses.Theexpectationwas that the students and postdocs could stay in Hostels of the universities they are visiting.However,giventhatthevisitswhichareundertakenunderthenetworkprojectareofsmallduration,of about fifteendays, itwas verydifficult toorganisehostels for them. Furthermore,manyof thenodes inFranceare laboratories rather thanuniversities (Annecy,Lyon,Paris-Saclay),which leavesthemwith no access to hostels. This issuewas brought to the notice of CEFIPRA, who agreed toenhance the per-diem for students also to Euro 100 per day. Further, because of ourcorrespondencewithCEFIPRA,CEFIPRAissuedspecificguidelinesonhowtoconductvisits.

c) Workshop at IISER Pune during Feb 2018. A collaborationmeeting is being planned during the last week of Feb 2018 at IISER, Pune.

B. Plan of work for the remaining period of the project a) Planned visits/work in year 2017-2018 We plan to receive all the requests for a visit to India/France for the next year (2018) around mid-December. However, a few of the visits and research activities are already being planned.

a) Edmond Iancu will be visiting TIFR during Feb 2018. b) SUSY 2017 : Several French scientists will be participating in this international series of

workshops being held for the first time in India, at TIFR, Mumbai. Several prominent French Scientists are coming to this conference, presenting lectures (Prof. Boudjema), and plenary talks (Profs. Belanger and Prof. Dudas).

c) During the last week of Feb 2018, at IISER Pune, we plan to organise a collaboration meeting on similar lines to the Kick-Off Meeting held in Bangalore last year. We hope to get several prominent French and Indian scientists together and the focus would be to form new collaborations which have not hitherto formed.

b) Physics Collaborative Research Goals Collaborative research will continue at the highest levels within the framework of the Network. The focus will continue to be on two main streams:

a) BSM Physics b) Quark-Gluon Plasma

We will adhere to the work programme we have set in the proposal (see Table 2.1). It is on this basis that discussions were geared to constitute the working groups which have been formed during the Kick-off meeting in Bangalore. Participants to these working groups will continue to work on their respective projects until they are complete and published. As mentioned earlier, the working groups have their own wiki page for a more efficient collaboration. Upon completion of some of these tasks a reorganisation of the structure of the working groups may be proposed. We hope there will be new working groups set up in the coming years tackling newer and more interesting problems as the need arises. We already foresee some merger between some working groups in view of the preliminary results that are shaping up. One example is the use of new techniques emerging from the exploitation of soft tracks to probe more in detail the search for monojets and mono-photons and their impact on the search of Dark Matter. An effort is being made such that different groups and subgroups gather the results of their investigations to build up a more general picture. Another objective that the Network has made possible is to arrive at a detailed review of a particular topic looked at from different angles, here we have in mind the issue of Dark

21

21

Matter and how the results of the LHC when analysed in terms of the tools we have developed for simplified models as well as with the help on the one hand of analysis tools and on the other hand with the input of the experimentalists in the Network could give strong constraints on some models of Dark Matter. Another example is the investigation of the properties of the Higgs. We would like to stress here that the framework set up is sufficiently geared up to tackle any new surprises either in the LHC data or from the astro-particle physics side. Just as we have seen in the 750GeV case, we expect an efficient and strong response from the collaboration members within the framework. Overall, we expect a strong scientific research performance in terms of publications, visibility (conferences, talks, posters etc) in the coming years. The community looks forward for news from this collaboration and there are many who have shown interest to be a part of it.

III ASSESSMENT Please give your own assessment of the way the project is going on. We would appreciate receiving your free and frank views. Please mention bottlenecks, if any, faced during the implementation of this project. You may also give any suggestions for improving the method of implementation of this project in particular and all CEFIPRA projects in general.

Overall, we are quite satisfied about the progress of the work and the way collaborations between the different nodes and laboratories have sprung up or strengthened, particularly in the last year. Although a lot of work had been taking place (even before the approval) of the project, we believe that the kick-off meeting was a great stimulator, especially between the young members of the Network and the senior members. Integration of all on a equal basis through a common collaborative platform (wiki) help speed up exchanges. At the start of the project, we were also blessed by the excitement over the 750GeV excess, although this excess vanished when more data was collected, the excitement was also a source of many exchanges some of which leading to building of new models. We have put great emphasis also on training. Many students and post-docs benefited from visits to France where quite a few projects initiated during the kick-off meeting were worked out thoroughly during these visits. As indicated in our proposal, it was always our aim to make the most of the CEFIPRA budget and strive to involve a maximum number of physicists from both our countries in the field of high energy physics. Boosted by the successful application to CEFIPRA we looked for support from other sources in particular the French CNRS while working closely with the laboratories of the Network in order that some partial support for local expenses be covered by the participants institutes. Not only we secured funding for a LIA but also were able to convince the heads of our laboratories to chip in. This explains also the large number of projects and visits which led to so many successful publications.

We thank CEFIPRA for the flexibility it provides in arranging the visits and of course in organising them. This provides us freedom to distribute the visits over the course of the time period of the project instead of on a yearly basis. This kind of flexibility is very crucial for the success of a network project like ours, and we reiterate our appreciation for CEFIPRA on that matter.

1V Request for No Cost Extension.

While officially the project started during Jan 2016, it only really took off after the Kick-off meeting in May 2016. Presently there are several projects going on, and many new are starting. Furthermore, we have a flux of new members (mostly students and postdocs) who all want to participate actively in the collaboration. Given that we have used only 20% of the budget so far, we would like to already request a no-cost extension for one more year, ie, up Jan 2020 so that all the money is effectively spent. From the collaboration and publications point of view, the project is already a success, so we expect the success to continue also with the new members.
