  We argue that the distribution of hadrons near the longitudinal light-cone in
central high-energy pA collisions is computable in weak coupling QCD. This is
because the density of gluons per unit transverse area in the dense target at
saturation provides an intrinsic semi-hard momentum scale, Qs. We predict that
the longitudinal distribution of (anti-)baryons and mesons steepens with
increasing energy and atomic number of the target, and that the transverse
momentum distribution broadens. We show that the evolution of high moments of
the longitudinal net baryon distribution with Qs is determined by the anomalous
dimension gamma_qq.
