摘要

The charged-particle pseudorapidity density dNch/dη has been measured for Au+Au collisions at √sNN=130 GeV at RHIC, using the PHOBOS ap- paratus. The total number of charged particles produced for the 3% most central Au+Au collisions for |η| ≤5.4 is found to be 4200±470. The evolution of dNch/dη with centrality is discussed, and compared to model calculations and to data from proton-induced collisions. The data show an enhancement in charged-particle production at mid-rapidity, while in the fragmentation regions, the results are consistent with expectations from pp and pA scattering.
