CENTRALITY DEPENDENCE OF CHARGED HADRON SPECTRA AT FORWARD RAPIDITIES IN Cu+Cu COLLISIONS AT (sNN)~2 1/2=200 GeV

摘要

We present preliminary results for Cu+Cu collisions at (sNN)~2 1/2=200 GeV at the BRAHMS experiment from charged hadron spectra and nuclear modification factors as a function of centrality and pseudo-rapidity. Deviations from binary scaling at intermediate and high-pT reveal themselves as a suppression in the transverse momentum distribution of produced particles. The observed suppression depends on the volume of the interaction region through which produced hadrons have to travel. While there is still significant suppression, Rcp seems to depend very little on pseudo-rapidity.
