摘要: Nuclear shadowing effects are checked in the production of direct photons and neutral pions heavy-ion collisions at RHIC/LHC energy within a next-to-leading order perturbative QCD parton model. The transverse momentum dependence nuclear modification factors is presented p + A to distinguish different parameterizations for effects. Our numerical results show that central factor more sensitive than pion hadrons, it powerful observable discriminate distributions.
