摘要
We analyze the forward-backward multiplicity correlation coefficient as measured by STAR. We show that in the most central Au + Au collisions bins located symmetrically around eta = 0 with large separation in pseudorapidity are more strongly correlated than bins located asymmetrically with smaller separation. In proton-proton collisions the opposite effect is observed. It suggests a qualitatively different behavior of the two-particle correlation as a function of pseudorapidity sum in p + p and Au + Au collisions.
