摘要
Integrated two particle correlation functions have been extracted from charge particle multiplicity density fluctuations in pseudorapidity space by analyzing Au+Au collision events at S_(NN)^(1/2)=200GeV taken by RHIC-PHENIX.The correlation lengths as a function of the number of participants N_p indicate a non monotonic increase at around N_p=100 and the corresponding energy density based on the Bjorken picture isε_(Bj)τ～2.SGeV·fm^(-2).This could be a symptom of a critical behavior.
Integrated two particle correlation functions have been extracted from charge particle multiplicity density fluctuations in pseudorapidity space by analyzing Au＋Au collision events at √sNN= 200GeV taken by RHIC-PHENIX. The correlation lengths as a function of the number of participants Np indicate a non monotonic increase at around Np = 100 and the corresponding energy density based on the Bjorken picture is eBj T - 2.5GeV.fm^-2. This could be a symptom of a critical behavior.
