Abstract
The PHOBOS experiment has measured the charged particle multiplicity at midrapidity in Au+Au collisions at roots(NN)=200 GeV as a function of the collision centrality. Results on dN(ch)/deta\(\eta\<1) divided by the number of participating nucleon pairs [N-part]/2 are presented as a function of [N-part]. As was found from similar data at roots(NN)=130 GeV, the data can be equally well described by parton saturation models and two-component fits, which include contributions that scale as N-part and the number of binary collisions N-coll. We compare the data at the two energies by means of the ratio R-200/130 of the charged particle multiplicity for the two different energies as a function of [N-part]. For events with [N-part]>00, we find that this ratio is consistent with a constant value of 1.14+/-1(stat)+/-5(syst).
