Comparisons of Publication Record• PHENIX: 63 papers, 4976 citations

– 41 PRL, 19 Phys. Rev, 2 PLB, 1 NPA– 5 Famous, 11 Very Well-Known, 12 Well-Known

• Most cited paper at RHIC: jet quenching paper at 398

• STAR has – More papers: 72 vs. 63– More Famous papers: 6 vs. 5– More citations: 5648 vs. 4976

• STAR has many more long papers (26 Phys. Rev.), but – With push after QM2006, PHENIX has caught up on PRL this year

• Comparison with experiments from other colliders– CDF: 362 (PRL+PLB+Phys. Rev.), 20223 citations

• 3 “Renowned” (500+ cites), 3 Famous• Citation rate: 56/paper, rather than 73/paper in STAR’s case• Publishing since 1994, rather than 2001; still >~ double rate of papers/year

– D0: 191 (PRL+PLB+Phys. Rev.), 8350 citations• 1 Renowned paper, 0 Famous

Papers by Year

• Maturation of program: shift from PRL to PRC over time– Noticed in report at a collaboration meeting in 2004

• Submitted papers this year to date on track– 5 submitted papers in advanced process of review, 1 recently submitted to PRL

Submitted and in advanced stages of

referee review

Keeping paper publication going

• 7 papers with the journals– Most recent: 2005 jet ALL

• 2 papers in collaboration review– d+Au resonance paper– Charm production paper– Institution review has started

• 14 papers in God Parent Committee

• Rate is on track, but hope to see a burst of new papers next year after run 7 data fully available

• Institutional review instituted– Appears to be working: more people read the papers– Needs a bit of tweaking to ensure timeliness

Conferences: Upcoming

Recent release of 2006 ALL measurement at DNP

Quark Matter 2008 in February: must and will make a good showing• Thursday discussion: QM plans from PWGs

Datasets• 2005 Cu+Cu (P07ib): finished production this summer

– Full dataset: 200 GeV and 62 GeV– SVT and SSD calibrated– However, overwrite bug from BEMC to SSD makes use questionable

• 2007 Au+Au: Dramatic increase in luminosity and quality– 75M minbias events with tight vertex cut (5 cm online)

• Should have ~90% acceptance to pass through all layers of silicon• 75M “minbias” events (6 b?) is ~13 ub-1

– 600 ub-1 integrated: equivalent to 24 pb-1 p+p events (with caveats)• Vertex cut and detector sets changes luminosity per trigger• Upsilon (30 cm vertex): 300 ub-1

• Btag (4 GeV+tight vertex): 50 ub-1

• Comparison to run 4: 50 ub-1 ½ barrel BEMC HT with wide vertex; central trigger integrated 30 ub-1

• Continual need to access older datasets– With Xrootd issues, periodic need to reassess data distribution

2007 Dataset

• Express streams– Gamma: 1 M

– MTD: 0.5 M

– Upsilon: 5 M

– UPC: 2 M (fast)

– UPC-Jpsi: 7k

– Btag*: 1.5M

2007Production2*: 19 M

2007ProductionMinBias*: 62 M

* Requires SVT and SSD calibration

Timescale: express stream w/o SVT now, Btag November, rest ~4 months

For QM2008: gamma, upsilon safe; Btag possible; rest not possibleEstimate from past June is ~20M events/month

Run 8

• BUR goals:– d+Au: 10 weeks, 30 nb-1slow/60 nb-1 fast sampled

Saturation search primary goal

– p+p: 12 weeks, 30 pb-1 slow sampledSpin running primary goal for first measurement of x dependence of G

– Other goals with an eye towards run 9• Reference triggered datasets: electrons with low material budget, Upsilon,

gamma-jet

• Collision rates are high (500 kHz d+Au, 1 MHz p+p) and we do not have DAQ1000

• Discussion Friday: keep deadtime low– d+Au: Estimate ~160 nb-1 delivered, need to keep deadtime to ~50% to

achieve 30 nb-1 sampled– p+p: Estimate ~90 pb-1 delivered, need to keep deadtime to 35% to

achieve 30 pb-1 sampled– Current sum of requests: > 100% dead. Hard decisions needed.

Future initiatives

• Number of committees to investigate specific issues– Shorter term: DSM (today), VPD (Thursday)– Longer term: FTPC and PMD plans (Thursday)

• Beam energy scan of growing interest for run 10– New focus group formed– Parallel meeting Wednesday, plenary Thursday

• Heavy Flavor Tracker a major detector upgrade for the future– Parallel session Tuesday

10/15/2007 Dunlop, Welcome and Overview, Analysis Meeting 2007

12

Future runs

• Current plans in the 2007 BUR– Run 9: DAQ1000 + large fraction of TOF

• Au+Au: electrons, dileptons, photons, Upsilon; large datasets and luminosity with minimal material

• p+p: Finish 200 GeV longitudinal running

– Run 10: Full TOF brings Beam Energy Scan• Au+Au: search for the critical point with identified particle correlations

• p+p: first run for 500 GeV. FGT?

• Beyond run 10: time to start thinking– Great opportunities with upgraded detectors and luminosity– Run 11: EBIS should be online. U+U?– HFT installation and ramp-up of RHIC II luminosity

Cross-PWG Discussions

• Analysis meeting: time to get everybody together in one room to hash out analysis issues

• Friday morning: attempt on a few focused topics– V2, correlations and fluctuations– Triggered correlations at high pt: electrons, photons, etc.– Cu+Cu vs. Au+Au: strangeness and spectra

• Additionally, a number of joint PWG meetings

Encourage cross-PWG discussions: this is the point
