Query: Saturating Cronin effect in ultrarelativistic proton-nucleus collisions   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.
