Nuclear effects in hadron production in nucleon-nucleus collisions

Popis výsledku v původním jazyce

We investigate nuclear effects in production of large-pT hadrons in nucleon-nucleus collisions corresponding to a broad energy range from the fix-target up to RHIC and LHC experiments. For this purpose we use the QCD improved parton model including the intrinsic parton transverse momenta. This model is firstly tested reproducing well the data on pT spectra of hadrons produced in proton-proton collisions at different energies. For investigation of large-pT hadrons produced on nuclear targets we include additionally the nuclear broadening and the nuclear modification of parton distribution functions. We also demonstrate that at large-pT and at forward rapidities the complementary effect of initial state interactions (ISI) causes a significant nuclear suppression. Numerical results for nucleus-to-nucleon ratios are compared with available data from the fix-target and collider experiments. We perform also predictions at forward rapidities which are expected to be measured in the future at
