Abstract

Particle production of identified charged hadrons, π±,K±, p, and p̄ in Au+Au collisions at sNN= 200 GeV, has been studied as a function of transverse momentum and collision centrality at y=0 and y~1 by the BRAHMS experiment at Brookhaven National Laboratory's Relativistic Heavy-Ion Collider. Significant collective transverse flow at kinetic freeze-out has been observed in the collisions. The magnitude of the flow rises with the collision centrality. Proton and kaon yields relative to the pion production increase strongly as the transverse momentum increases and also increase with centrality. Particle yields per participant nucleon show a weak dependence on the centrality for all particle species. Hadron production remains relatively constant within one unit around midrapidity in Au+Au collisions at sNN= 200 GeV.
