Negatively Charged Hadron Spectra in Au+Au Collisions at sqrt(s_NN) = 130 GeV

Negatively charged hadron (h-) production in Au+Au collisions at BNL-RHIC is studied with the STAR experiment. Results are presented on h- multiplicity, pseudorapidity and transverse momentum distributions at sqrt(s_NN) = 130 GeV.Comment: 4 pages, 4 figures. Presented at Quark Matter 200

Generalized scaling of the transverse mass spectrum at the Relativistic Heavy-Ion Collider

We argue that the transverse mass spectra of identified hadrons as measured in gold-gold collisions at BNL's Relativistic Heavy-Ion Collider (RHIC) follows a generalized scaling law. Such a scaling behavior is motivated by the idea of a Color Glass Condensate, or more generally, saturation of the gluon density. In particular, we describe the shapes of transverse mass spectra as a function of centrality. This scaling of the transverse mass spectrum is shown to be consistent with previously observed scaling of multiplicity with centrality.Comment: 15 pages, 6 figures, refs. updated, version to appear in Nucl.
