RHIC data and the multichain Monte Carlo DPMJET-II

Abstract

Using data from RHIC we are able to systematically improve the two-component Dual Parton Model (DPM) event generator DPMJET-III. Introducing percolation parametrized as fusion of chains the model describes multiplicities and pseudorapidity distributions in nucleus-nucleus collisions at all centralities. Guided by the d-Au data from RHIC we recalibrate the model to obtain collision scaling in h-A and d-A collisions.Comment: 8 pages, Based on a poster submitted to the 17th International Conference on Ultra Relativistic Nucleus Nucleus Collisions, Jan. 11-17, Oakland,California US
