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 root 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 Np = 100 and the corresponding energy density based on the Bjorken picture is epsilon(Bj) iota similar to 2.5GeV center dot fM(-2). This could be a symptom of a critical behavior.
