Query: Absence of Suppression in Particle Production at Large Transverse
  Momentum in sqrt(s_NN) = 200 GeV d+Au Collisions   Transverse momentum spectra of charged hadrons with p_T < 8 GeV/c and neutral
pions with p_T < 10 GeV/c have been measured at mid-rapidity by the PHENIX
experiment at RHIC in d+Au collisions at sqrt(s_NN) = 200 GeV. The measured
yields are compared to those in p+p collisions at the same sqrt(s_NN) 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.
