Particle production at forward rapidity in d+Au and Au+Au collisions in STAR experiment at RHIC

Abstract

We present the recent results from the STAR experiment on charged and neutral particle measurements at the forward rapidity in d+Au collisions at sqrt{s_{NN}} = 200 GeV and Au+Au collisions at sqrt{s_{NN}} = 62.4 GeV. The nuclear modification factor for charged and neutral hadrons in d+Au collisions are presented. Measurements of Lambda and anti-Lambda production at forward rapidity and the variation of net baryon density as a function of collision centrality are discussed. We have also studied the limiting fragmentation of photons and charged particles in Au+Au collisions. The photons and charged particles separately follow the energy independent limiting fragmentation behaviour. However they have been observed to follow a different centrality dependence of limiting fragmentation.
