We study nuclear effects in production of large−pT hadrons on nuclear targets at different energies corresponding to RHIC and LHC experiments. For calculations we employ the QCD improved parton model including the intrinsic parton transverse momenta and the nuclear broadening. Besides nuclear modification of parton distribution functions we include also the complementary effect of initial state interactions causing a significant nuclear suppression at large−pT and at forward rapidities violating so the QCD factorization. Numerical results for nucleus-to-nucleon ratios are compared with available data from experiments at RHIC and LHC. We perform also predictions for nuclear effects at LHC expected at forward rapidities.
