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 gives larger incoherent diffraction cross sections than the Gaussian approximation for photon-nucleus collisions because the latter is invalid for four-gluon starting correlators.
The gluon-initiated trijet channel in forward pA collisions is calculated at leading order in CGC, revealing a four-gluon vertex structure matching instantaneous terms and showing how rapidity and collinear divergences feed into JIMWLK evolution and PDF/FF kernels.
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.
