Large pT Hadron Spectra in pp, pA and AA Collisions

Abstract

Large pT particle spectra in p+p, p+A and A+B collisions at different energies are calculated in a QCD parton model. Intrinsic transverse momentum, its broadening due to initial multiple parton scattering are included. These calculations are meant to estimate the normal nuclear effects (parton shadowing, pT broadening or Cronin effect) in high pT hadron spectra in heavy-ion collisions. Comparisons of these calculations with experimental data will help to determine the effect of jet quenching.
