Nu Xu6/12 ”DNP“, Newport Beach, California, December , 2012 Higher Moment: Net-charge STAR Preliminary 1)Preliminary net-charge results: efficiency, decay, … effects under study 1)Higher statistics data needed below 20 GeV - HRG Model: K. Redlich et al, private communications STAR: D. McDonald, QM2012

Nu Xu7/12 ”DNP“, Newport Beach, California, December , 2012 STAR net-proton results: 1)All data show deviations below Poisson beyond statistical and systematic errors in the 0-5% most central collisions for κσ 2 and Sσ at all energies. 2)UrQMD model show monotonic behavior 3)Higher statistics needed for collisions at √s NN < 20 GeV Net-proton Higher Moments STAR Preliminary STAR: X.F.

Nu Xu9/12 ”DNP“, Newport Beach, California, December , 2012 URQMD Net-protonNet-baryon 1)Simulations are done with the same experimental cuts 2)For κ*σ 2 net-p and net-B behavior similarly: a) peripheral centrality bins, values are above unity b) at most central collisions, the value below at lower beam energy

Nu Xu11/12 ”DNP“, Newport Beach, California, December , 2012 Summary and Outlook 1)Transport model results for net-proton are consistent with experimental observations 2)In these simulations, no significant difference between net-p and net-B 3)At lower beam energies, baryon conservation pushes the value of κ*σ 2 below unity Outlook: RHIC BES-II is needed in order to collect sufficient data for collisions at √s NN < 20 GeV RHIC provides unique opportunities for exploring matter with QCD degrees of freedom!
