Abstract

Transverse momentum spectra of charged hadrons with [Formula presented] and neutral pions with [Formula presented] have been measured at midrapidity by the PHENIX experiment at BNL RHIC in [Formula presented] collisions at [Formula presented]. The measured yields are compared to those in [Formula presented] collisions at the same [Formula presented] scaled up by the number of underlying nucleon-nucleon collisions in [Formula presented]. The yield ratio does not show the suppression observed in central [Formula presented] collisions at RHIC. Instead, there is a small enhancement in the yield of high momentum particles.
