Saturating Cronin effect in ultrarelativistic proton-nucleus collisions
arXiv:nucl-th/9903012 · doi:10.1103/PhysRevC.61.021902
Abstract
Pion and photon production cross sections are analyzed in proton-proton and proton-nucleus collisions at energies 20 GeV < s^1/2 < 60 GeV. We separate the proton-proton and nuclear contributions to transverse-momentum broadening and suggest a new mechanism for the nuclear enhancement in the high transverse-momentum region.
