Abstract
We present the two-loop QCD amplitudes for the production of two photons and a jet at hadron colliders with full-color dependence. This is the first time that radiative corrections for a five-particle scattering process have been computed beyond the leading-color approximation at this perturbative order in QCD. The results presented in this Letter will be crucial to guaranteeing reliable predictions with unprecedented precision for diphoton production at hadron colliders. The methodologies that we describe lead to a significant simplification of the calculation and their applicability extends to a wider range of five-point scattering processes.
Highlights
The past two decades have witnessed impressive developments in our understanding of scattering amplitudes in quantum field theory, both in supersymmetric theories such as N 1⁄4 4 super Yang-Mills, and in phenomenologically relevant ones such as quantum chromodynamics (QCD)

The increasing interest devoted to formal aspects of scattering amplitudes is motivated by their fundamental role in providing accurate theoretical predictions to interpret the experimental data collected at particle colliders like the CERN Large Hadron Collider (LHC)
Summary
The past two decades have witnessed impressive developments in our understanding of scattering amplitudes in quantum field theory, both in supersymmetric theories such as N 1⁄4 4 super Yang-Mills, and in phenomenologically relevant ones such as quantum chromodynamics (QCD). We present the two-loop QCD amplitudes for the production of two photons and a jet at hadron colliders with full-color dependence.
