Polish participation in Icarus Test in Pavia

• One of the triggers was prepared by PL groups.• Shifts• Data analysis: - study of the propagation of scintillation light

- reconstruction of 0 events - reconstruction of muon energies - data compression

(7 papers published in 2003-2006)

Icarus in LNGS (examples) • modification of the readout electronics• neutrino interactions (analytical and MC) • procedures for tau event selection• a check of mechanical parameters for cryostats

Future accelerator long-baseline experiment: T2K

Polish neutrino group

However the road to additional ICARUS modules appears to be a very rocky one…….

Therefore we are using the acquired expertise in LAr techniquein simulations for T2K-LAr. We also consider hardware contributions to T2K.

Topical Neutrino conferences organized in PL:

1. Nuclear effects in neutrino interactions20th Max Born Symposium, Dec. 7-10, 2005, Wrocław, Poland

2. Cracow Epiphany Conference on Neutrinos and Dark Matter, Cracow, Poland, 5-8 January 2006.


Summary Strength of experimental neutrino physics in PL:

We are involved in the most successful neutrino experiments Elsevier awarded its SCOPUS award for the most cited science

papers with Polish authors for publications in neutrino physics

The groups (experimental and theoretical) collaborate very closely - with regular meetings/workshops in Katowice, Kraków, Warszawa or Wrocław. This is very helpful in sharing our expertise in various fields.

9 institutions, 39 physicists (18 senior & 21 junior)

Our Weakness:my personal view

We are involved in too many different projects and our initial plan to unify and to have significant contribution in one attractive experiment has not come to fruition yet.

To help that we organize a Polish Neutrino Network this afternoon.
