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.), 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

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

10/15/2007Dunlop, Welcome and Overview, Analysis Meeting Keeping paper publication going 7 papers with the journals –Most recent: 2005 jet A LL 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

10/15/2007Dunlop, Welcome and Overview, Analysis Meeting Conferences: Upcoming Recent release of 2006 A LL measurement at DNP Quark Matter 2008 in February: must and will make a good showing Thursday discussion: QM plans from PWGs

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

10/15/2007Dunlop, Welcome and Overview, Analysis Meeting 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 possible Estimate from past June is ~20M events/month

10/15/2007Dunlop, Welcome and Overview, Analysis Meeting Run 8 BUR goals: –d+Au: 10 weeks, 30 nb -1 slow/60 nb -1 fast sampled Saturation search primary goal –p+p: 12 weeks, 30 pb -1 slow sampled Spin 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.

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

10/15/2007Dunlop, Welcome and Overview, Analysis Meeting Future runs Current plans in the 2007 BUR –Run 9: DAQ 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

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