Description
We study nuclear effects in production of large-p_{T} 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 nuclear broadening. This model is firstly tested reproducing well the data on p_{T} spectra of hadrons produced in proton-proton and proton-nucleus collisions at different energies.
Besides nuclear modification of parton distribution functions
we observe that the complementary effect of initial state interaction causes
rather strong nuclear suppression at large p_{T} and 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 in production of high-p_{T} hadrons at forward rapidities
which are expected to be measured in the future at LHC.
