FORWARD-BACKWARD MULTIPLICITY CORRELATIONS IN Au+Au COLLISIONS AT $\sqrt{s_{NN}} = 200\, {\rm GeV}$

Abstract

The study of correlations among particles produced in different rapidity regions may provide understanding of the mechanisms of particle production. Correlations that extend over a longer range are observed in hadron-hadron interactions only at higher energies. Results for short and long-range multiplicity correlations (Forward-Backward) are presented for Au + Au collisions at [Formula: see text]. The growth of long range correlations are observed as a function of the pseudorapidity gap in central Au + Au collisions. The Dual Parton model and Color Glass Condensate phenomenology have been explored to understand the origin of long range correlations.
