High p inclusive charged hadron distributions in Au+Au collisions at [formula] at RHIC

Abstract

This thesis reports the measurement of the inclusive charged particle (h

h −) p⊥ spectra for 1.7 < p⊥ < 6 GeV/c at midrapidity (|η| < 0.5) as a function of various centrality classes in Au+Au collisions at √sNN=130 GeV. Hadron suppression is observed relative to both scaled NN and peripheral Au+Au reference data, possibly indicating non-Abelian radiative energy loss in a hot, dense medium.
