Abstract

It is argued that for very high-energy pA collisions the production of leading hadrons, most notably that of forward baryons and antibaryons, should be computable in weak coupling QCD. This is because the large gluon density of the blackbody target per unit transverse area at small x provides an intrinsic semihard momentum scale. Resuming higher-twist contributions to the quark-nucleus cross section a depletion of forward hadron production is expected, which becomes stronger as the atomic number of the target nucleus and/or the energy increase.
