Abstract

We study the effect of spatially homogeneous and inhomogeneous shadowing on J/\ensuremathψ production in deuterium-nucleus collisions. We discuss how the shadowing and its spatial dependence can be measured by comparing central and peripheral dA collisions. These event classes may be selected by using gray protons from heavy ion breakup and events where the proton or neutron in the deuterium does not interact. We find that inhomogeneous shadowing has a significant effect on central dA collisions, larger than expected in central AA collisions. Results are presented for dAu collisions at √s_NN=200 GeV and dPb collisions at √s_NN=6.2 TeV.
