[en] We present the computation of the direct photon production cross-section in
perturbative QCD to all orders in the limit of high partonic center-of-mass energy. We show how the high-energy resummation can be performed consistently in the presence of a collinear singularity in the final state, we compare our results to the fixed order NLO cross-section in MS scheme, and we provide predictions at NNLO and beyond. | |
