文摘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.
