Shadowing and absorption effects on J/{psi} production in dA collisions

We study medium modifications of J/{psi} production in cold nuclear media in deuterium-nucleus collisions. We discuss several parametrizations of the modifications of the parton densities in the nucleus, known as shadowing, an initial-state effect. We also include absorption of the produced J/{psi} by nucleons, a final-state effect. Both spatially homogeneous and inhomogeneous shadowing and absorption are considered. We use the number of binary nucleon-nucleon collisions as a centrality measure. Results are presented for d+Au collisions at {radical}(S{sub NN})=200 GeV and for d+Pb collisions at {radical}(S{sub NN})=6.2 TeV. To contrast the centrality dependence in pA and dA collisions, we also present p+Pb results at {radical}(S{sub NN})=8.8 TeV.
