  1. Hungary in PHENIX experiment at RHIC, BNL a sustained Fulbright Alumni Initiative story T. Csörgő MTA KFKI RMKI, Budapest, Hungary • A Hungarian team in PHENIX - milestones and achievements: • RHIC Scientists serve up “Perfect Liquid”, April 18, 2005 • AIP Top Physics Story 2005 • Hungarian chronology and results in PHENIX • Perfect fluids: analysing and understanding the observations • Exact (i.e. not numerical) integrals of fluid dynamics • Evidence for hydrodynamic scaling in RHIC data • A fluid of quarks at RHIC • Projected time schedule and manpower • Future plans

  2. Approved upgrades: PHENIX experiment at RHIC, BNL PHENIX: Pioneering High ENergy eXperiment (high energy physics) RHIC: Relativistic Heavy Ion (and polarized proton) Collider on Long Island, near New York, NY, USA 4 experiments, PHENIX is one of the two “big” RHIC Experiments BNL: Brookhaven National Laboratory, one of the 10 National Labs funded by DOE Goal of PHENIX/RHIC: to produce the matter that filled the Universe in a glimpse after the Big Bang By colliding Au+Au @ Ecms(NN) = 200 GeV (also at 130 , 62.4 and 19.6 GeV) also Cu+Cu,polarized p+polarized p andd+Aucollisions Hungarian institutional participation in the PHENIX-Hungary sub-collaboration: Debrecen University, Debrecen, Hungary ELTE University, Budapest, Hungary KFKI Research Institute for Particle and Nuclear Physics, Budapest, Hungary “RHIC has a bright future ... will likely survive the nextdecade” (~ 2020) (S. Aronson, BNL Director, Oct/3/06)

  3. PHENIX • photons, electrons muons and hadrons • Investigates all stages of the reaction • Penetrating probes: early state of the reaction • Hadrons

  4. 1st milestone: new phenomena Suppression of high pt particle production in Au+Au collisions at RHIC

  5. 2nd milestone: new form of matter d+Au: no suppression Its not the nuclear effect on the structure functions Au+Au: new form of matter !

  6. 3rd milestone: Top Physics Story 2005 http://arxiv.org/abs/nucl-ex/0410003

  7. Hungarian chronology in PHENIX T. Cs. Fulbright Advanced Research Award (1998) theoretical physics w M. Gyulassy, Columbia Uni. + initiation of a PHENIX group in Hungary with W.A.Zajc, PHENIX Spokesperson (Columbia Uni.) and with J. Zimányi (1931 - 2006) Head, Science Council, KFKI RMKI 1998-1999: Fundraising period T. Csörgő: Fulbright Alumni Initiative Award for the organization of PHENIX-Hungary 2000- : Hungarian contributions to PHENIX started: contribution to centrality determination (A. Ster, KFKI RMKI/MFA) P. Tarján, V. Veszprémi (Debrecen) contribution to PHENIX EMCal quality assurance, calibrations, lead by G. David 2002: Memorandum of Understanding signed: between PHENIX Experiment, Physics Department of BNL, Debrecen University, ELTE University and KFKI RMKI, Budapest 2006: Memorandum of Understanding between PHENIX and PHENIX-Hungary Institutions has been extended till 2011

  8. Hu in PHENIX: chronology projection - 2011 Cutting edge advantage:Extended MoU with PHENIX: no running cost! KFKI RMKI: 3 faculty + 1 student ELTE group: 1 faculty + 2 students Debrecen: 0 faculty + 1 visiting prof + 2 grad. students + 2 others PHENIX: production mode, exciting live physics in both cases: theoretical activity, desire to understand results. Unique nature of the group: students are trained both in theory and in experiment and have to be able to prepare papersin both. 2006: fundraising 2007-2011: PHENIX data taking shifts, data analysis PHENIX upgrades: interested but no funds for this Electronics, PHENIX DAQ: same Data production: same Software infrastructure and analysis: PHENIX-Hungary cluster 38 CPU-s, used for simulations in Global/Hadron PWG, PPG05 Shortage of funds in Hungary (OTKA/government budget problem): limits manpower, most serious risk Upgrade plans for PHENIX-Hu: computing+grid, proposals submitted

  9. PHENIX Hungary and summary of contributions: 12 Hungarian authors and three Hu Institutions on PHENIX review paper (White Paper, Nucl, Phys, A (2005). By now: SLAC Spires famous paper, AIP Top Physics Story in 2005 Debrecen University (mentor prof. P. Raics): Dávid Gábor (BNL/Debrecen) founder of the group, 1996- . Founding member of PHENIX: design, fund raising, construction, operation, data taking and analysis. Important discovery: suppression of high ptp0 production in central Au+Au collisions (2001). Cover page of PRL and top-cited paper at RHIC. In the control experiment d+Au the suppression of high pt particle production is not seen (2003), hence new form of matter is created in Au+Au collisions at RHIC. Author of several analysis notes, group leader in PHENIX. Visited Hungary during his holidays, at various times on his budget. Trained several Debrecen students who contributed significantly to EMCal related observations in PHENIX. A need for local PHENIX team leader .

  10. Debrecen PhD Students Péter Tarján (PhD?), József Imrek, V. Veszprémi, Róbert Vértesi (PhD) Experts of PHENIX EMCal, contibuted to neutral pion spectra in 200 GeV-es Au+Au. Authors of a number if analysis notes. EMcalorimter: improvement and modernization of its simulatiions and calibrations. Contributions to observation of direct gamma production by quarks. Important contributions to fast Monte-Carlo of hadronic gamma production, needed to reconstruct direct photons below 6 GeV. Reconstruction and timing: contribution to 11 PHENIX papers in 2005. Note: all pictures taken during PHENIX data taking runs (run3-run6)

  11. Contributions from ELTE: Excellent students Máté Csanád:PHENIX ZDC on-line and off-line calibration, HBT and spectrum analysis, contributed to the recongnition of perfect fluid picture, Fulbright Student Award to SUNY at Stony Brook.
