Abstract:
In this work, we review the general aspects of the high energy resummation technique. Recently derived results for high
energy resummation of direct photon
production are matched to NLO computations, and their implications
at the Tevatron and at the LHC are explored. The effects of
resummation are compared to various
sources of theoretical uncertainties like
PDFs and scale variations. We show how the high--energy resummation procedure
stabilizes the logarithmic enhancement of the cross
section at high--energy which is present at any
fixed order in the perturbative expansion starting at NNLO.
