抄録
Transverse momentum spectra of charged hadrons with pT < 8 GeV/c and neutral pions with pT < 10 GeV/c have been measured at midrapidity by the PHENIX experiment at BNL RHIC in d + Au collisions at √sNN = 200 GeV. The measured yields are compared to those in p + p collisions at the same √sNN scaled up by the number of underlying nucleon-nucleon collisions in d + Au. The yield ratio does not show the suppression observed in central Au + Au collisions at RHIC. Instead, there is a small enhancement in the yield of high momentum particles.
