Abstract
We determine rapidity asymmetry in the production of charged pions, protons, and antiprotons for large transverse momentum (p T ) for d+Au collisions at s NN = 200 GeV. The rapidity asymmetry is defined as the ratio of particle yields at backward rapidity (Au beam direction) to those at forward rapidity (d beam direction).
