Nuclear Reaction Mechanisms and the Cronin Effect


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… (More)
