Study on higher moments of net-charge multiplicity distributions using a multiphase transport model

黄玲  马国亮  
【摘要】:The moments and moment products of conserved charges are believed to be sensitive to critical fluctuations,which have been adopted in determining the QCD critical point.Using a dynamical multiphase transport model,we reproduce the centrality and energy dependences of moments and moment products of net-charge multiplicity distributions in Au+Au collisions,measured by the Beam Energy Scan program at the RHIC.No non-monotonic energy dependence is observed.We infer that the moment products develop during the dynamical evolution of heavy-ion collisions.The observed difference based on the expectation of the Poisson baseline indicates a positive two-particle correlation between positively and negatively charged particles,which can arise from different dynamical processes at different stages.Therefore,to adopt moments and moment products of net-charge multiplicity distributions in determining the QCD critical point of relativistic heavy-ion collisions,it is essential to consider the dynamical evolution.
