`Next-to-leading order diphoton+dijet production at the LHC'

Abstract:
The production of a photon pair is a very important process at hadron
colliders. In particular, when it is associated to the production of two
hadronic jets, it constitutes an important background to Higgs boson production
via Vector Boson Fusion. In this talk I will present the result of a recent
next-to-leading order calculation of this process at the LHC. I will also give
a brief introduction to generalized unitarity techniques, which have been used,
through their numerical implementation in BlackHat, for the evaluation of the
one-loop contributions in this calculation.
