Description
I will present a computation of two-loop amplitudes contributing to W+2 photon production at the Large Hadron Collider. We adopt a hybrid approach where analytic results are derived for the leading colour contribution while the subleading colour amplitudes are evaluated numerically, both within the finite-field framework. The size of subleading colour contribution is studied, by evaluating the amplitudes on a small set of physical phase-space points.
