Abstract: We present the computation of the direct photon production cross-section inperturbative QCD to all orders in the limit of high partonic center-of-massenergy. We show how the high-energy resummation can be performed consistentlyin the presence of a collinear singularity in the final state, we compare ourresults to the fixed order NLO cross-section in MSbar scheme, and we providepredictions at NNLO and beyond.
