High-momentum inclusive charged hadron distributions in gold+gold collisions at center of mass energy = 130 GeV at RHIC.

摘要

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.
