Suppression of Hadrons with Large Transverse Momentum in Central Au+Au Collisions at (sNN) = 130 GeV
Abstract
Transverse momentum spectra for charged hadrons and for neutral pions in the range 1 GeV/c<pT<5 GeV/c have been measured by the PHENIX experiment at RHIC in Au+Au collisions at (sNN) = 130 GeV. At high pT the spectra from peripheral nuclear collisions are consistent with scaling the spectra from p+p collisions by the average number of binary nucleon-nucleon collisions. The spectra from central collisions are significantly suppressed when compared to the binary-scaled p+p expectation, and also when compared to similarly binary-scaled peripheral collisions, indicating a novel nuclear-medium effect in central nuclear collisions at RHIC energies.
