FORWARD-BACKWARD MULTIPLICITY CORRELATIONS IN Au+Au COLLISIONS AT (~S(NN))~2 1/2 = 200 GeV

摘要

The study of correlations among particles produced in different rapidity regions may pro vide 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 pre sented for Au+Au collisions at (~S(NN))~2 1/2 = 200 GeV. The growth of long range correlations are observed as a function of the pseudorapidity gap in central Au+Au collisions Trie Dual Par ton model and Color Glass Condensate phenomenology have been explored t|s understand the origin of long range correlations.
