Cronin effect at different energies: from RHIC to LHC

Using the QCD improved parton model we study production of hadrons with large transverse momenta p_T in proton-proton and proton-nucleus collisions at different energies corresponding to experiments at RHIC and LHC. For investigation of large-p_T hadrons produced on nuclear targets we include additionally the nuclear modification of parton distribution functions and the nuclear broadening calculated within the color dipole formalism. We demonstrate that complementary effect of initial state interactions causes a significant suppression at large p_T and at forward rapidities. We provide a good description of the Cronin effect at medium-high p_T and the nuclear suppression at large p_T in agreement with available data from experiments at RHIC and LHC. In the LHC energy range this large-p_T suppression expected at forward rapidities can be verified by the future measurements. (authors)
