Inclusive Prompt Photons from the Color Glass Condensate at NLO

The cross-section for photons radiated by quarks in proton-nucleus collisions at collider energies was obtained using the Color Glass Condensate framework, in the dense-dilute kinematics regime. We observe that the inclusive photon cross- section is proportional to all-twist Wilson line correlators in the nucleus. These correlators also appear in quark-pair production ; unlike the latter, photon production is insensitive to hadronization uncertainties and therefore more sensitive to multi-parton correlations in the gluon saturation regime of QCD.
