Resumo

Pion and photon production cross sections are analyzed in proton-nucleus collisions at energies $20 \mathrm{GeV}\mathrm{}\ensuremath{\lesssim}\sqrt{s}\ensuremath{\lesssim}60$ GeV using a phenomenological description for the proton-proton collision. We separate the proton-proton and nuclear contributions to transverse-momentum broadening and suggest a new mechanism for the nuclear enhancement at high ${p}_{T}.$
