Centrality dependence of high-pT hadron suppression in Au plus Au collisions at √sNN=130 GeV -: art. no. 202301

Inclusive transverse momentum distributions of charged hadrons within 0.2<6.0 GeV/c have been measured over a broad range of centrality for Au+Au collisions at root s(NN)=130 GeV. Hadron yields are suppressed at high p(T) in central collisions relative to peripheral collisions and to a nucleon-nucleon reference scaled for collision geometry. Peripheral collisions are not suppressed relative to the nucleon-nucleon reference. The suppression varies continuously at intermediate centralities. The results indicate significant nuclear medium effects on high-p(T) hadron production in heavy-ion collisions at high energy.
