Description
We report on a first NLO computation of photon production in p+A collisions at collider energies within the Color
Glass Condensate framework, significantly extending previous LO results. At central rapidites, our result is the
dominant contribution and probes multi-gluon correlators in nuclei. At high photon momenta, the result is directly
sensitive to the nuclear gluon distribution. We work within the dilute-dense approximaton where the NLO result contains two processes, the annihilation process and the
process with quark-antiquark pair and a photon in the final state. We provide a full analytical result as well as a numerical evaluation for the NLO inclusive cross section. These results are partially contained in [1602.01989][1] and [1609.09424][2].
