  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 2000- : Hungarian contributions to PHENIX started: ZDC Pisa simulation, 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 /TOTEM: building up, investment nature/ 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 2007-2008: TOTEM DAQ (*) 2008- TOTEM data taking and 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
