Two-particle correlation and finite size effects of rapidity bin in ultra-relativistic heavy-ion collisions

Two-particle correlation and finite size effects of rapidity bin in ultra-relativistic heavy-ion collisions 1 first-author 1 1 1 1 1 1 Institute of Particle Physics, Hua-Zhong Normal University, Wuhan 430079 Institute of Particle Physics, Hua-Zhong Normal University, Wuhan 430079 Using an aspect of rapidity bins with finite sizes the short-range and long-range behaviors of two-particle correlation, the connection of two particle correlation function with factorial moment and factorial correlator are investigated; and experimental data for 16 O+Em interactions at 14.6, 60 and 200 A GeV and 32 S+ 197 Au interactions at 200 A GeV are analyzed. It is shown that the bin-average of two-particle correlation function can naturally give a coordinate description of dynamical fluctuation such as the second order factorial moment〈 F 2 〉 and 1+1 order factorial correlator 〈 F 1,1 〉.
