Abstract：
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=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 is ε_Bjτ～2.5GeV.fm^－2. This could be a symptom of a critical behavior.
