We present measured J/psi production rates in d + Au collisions at root s(NN) = 200 GeV over broad ranges of transverse momentum (p(T) = 0-14 GeV/c) and rapidity (-2.2 < y < 2.2). We construct the nuclear-modification factor R-dAu for these kinematics and as a function of collision centrality (related to impact parameter for the d + Au collision). We find that the modification is largest for collisions with small impact parameters and observe a suppression (R-dAu < 1) for p(T) < 4 GeV/c at positive rapidities. At negative rapidity we observe a suppression for p(T) < 2 GeV/c then an enhancement (R-dAu > 1) for p(T) > 2 GeV/c. The observed enhancement at negative rapidity has implications for the interpretation of the observed modification in heavy-ion collisions at high p(T). DOI: 10.1103/PhysRevC.87.034904
