Abstract
The PHENIX experiment at the Relativistic Heavy Ion Collider has measured charged hadron yields at midrapidity over a wide range of transverse momenta (0.5 < p(T) < 10 GeV/c) in Au+Au collisions at roots(NN)=200 GeV. The data are compared to pi(0) measurements from the same experiment. For both charged hadrons and neutral pions, the yields per nucleon-nucleon collision are significantly suppressed in central compared to peripheral and nucleon-nucleon collisions. The suppression sets in gradually and increases with increasing centrality of the collisions. Above 4-5 GeV/c in p(T), a constant and almost identical suppression of charged hadrons and pi(0)'s is observed. The p(T) spectra are compared to published spectra from Au+Au at roots(NN)=130 in terms of x(T) scaling. Central and peripheral pi(0) as well as peripheral charged spectra exhibit the same x(T) scaling as observed in p+p data.
