abstract
We compute the production of quark-antiquark pairs in high energy collisions between a small and a large projectile, as in proton-nucleus collisions, in the framework of the Color Glass Condensate. We derive a general expression for quark pair-production, which is not k_t-factorizable. However, k_t-factorization is recovered in the limit of large mass pairs or large quark--anti-quark momenta. Our results are amenable to a simple interpretation and suggest how multi-parton correlations at small x can be quantified in high-energy proton/deuteron-nucleus collisions.

JIMWLK evolution produces systematically larger incoherent diffraction cross sections than the Gaussian Approximation in photon-nucleus collisions because the latter is invalid for four-gluon-exchange correlators.
Analytical CGC amplitudes and cross sections for forward g o q¯qg and g o ggg trijet production in pA collisions are obtained, with rapidity and collinear divergences shown to match JIMWLK and DGLAP evolution.
Comparison of SMASH and McDipper initial condition models shows agreement in longitudinal deposition at lower energies but substantial differences in energy and baryon deposition at higher center-of-mass energies.
