Inhomogeneous shadowing effects on J / psi production in dA collisions

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