5 PID at STAR 5 IKYoo for HIM

6 K/ , ,  vs. E CM 6  Excellent agreement with SPS results IKYoo for HIM

7 Freeze-Out Conditions 7  Statistical model fit to , K, p  Excellent agreements with pub.data  Clear centrality dependence of T IKYoo for HIM

8   KK 8  R CP in E CM dependence   /K ratio vs. theories IKYoo for HIM

9 Flow (v 2 ) of Charged Hadrons 9 IKYoo for HIM

10 Integrated v 2 vs. E CM 10  BES results fill gap between NA49 and 200GeV/u IKYoo for HIM

11 Particle – Antiparticle v2 11 IKYoo for HIM

12 Particle – Antiparticle v2 12 IKYoo for HIM

13 v 2 /ncq scaling 13  ncq-scaling for all particles holds up to 7.7 GeV   -meson results deviates from others at 11.5 GeV IKYoo for HIM

14 K(p)/  E-by-E fluctuations 14   (p/  ): monotonic increase  s(K/p): almost constant ; disagree with NA49 IKYoo for HIM

16 16 IKYoo for HIM

17 ALICE Data 17 IKYoo for HIM

18 Particle Production in pp/PbPb 18 IKYoo for HIM

19 RHIC vs. LHC 19  The same experiment under vastly different conditions IKYoo for HIM
