Charged Hadron Spectra in PHENIX

Abstract

PHENIX has measured transverse momentum spectra of charged particles at mid-rapidity up to 10 GeV/c in Au+Au collisions at sqrt{s}=200 GeV. For central collisions, the yield at high pT is significantly suppressed comparing to binary scaled p+p data, and this suppression is stronger than observed at 130 GeV. Above 4 GeV/c, the deficit of high momentum particles is almost independent of pT.
