Production of Two Photons and a Jet Through Gluon Fusion

Abstract

We have computed the cross-section and distributions for the production of two photons and a jet via the process $gg\to \gamma \gamma g$. In the Standard Model, this process occurs at the one-loop level through pentagon and box diagrams. We show that at the LHC this is a significant mechanism for the production of the two photons and a jet. This process is also an important background to the Higgs boson production, when the Higgs boson decays into two photons. We also explorethis process at the Tevatron.
