Transverse and longitudinal dynamics at RHIC

Abstract

The BRAHMS collaboration measured inclusive identified hadron spectra in the wide rapidity range (0 < y < 3.5) for Au+Au and p+p collisions at √ sNN = 62.4 and √ sNN = 200 GeV. In this proceeding we present a set of observables, namely dN/dy rapidity dependence of pions, protons and anti-protons, anti-particle to particle ratios and the centrality dependence of net-proton distribution measured in Au+Au collision √ sNN = 200 GeV.We also present rapidity evolution of p/π ratio measured in the the same reaction. These results are discussed as to what constrains they can put on the models that account for baryon transport both in the longitudinal and transverse direction.
