Abstract

The influence of nuclear multiscattering and shadowing on pion spectra is investigated in pA collisions from CERN SPS to RHIC energies. The calculations are performed in a next-to-leading order (NLO) pQCD-improved parton model, including intrinsic partonic transverse momentum distributions. The nuclear modification of the pion spectra (Cronin effect) is considered at different targets in a wide energy range. Theoretical predictions are displayed for planned pA experiments at CERN SPS and recent dAu experimental results are analysed at RHIC.
