Two-loop amplitudes for $\mathcal{O}({\alpha }_s^2)$ corrections to $W\gamma \gamma$ production at the LHC

Simon Badger, Heribertus Bayu Hartanto, Zihao Wu +2

We present the two-loop helicity amplitudes contributing to the next-to-next-to-leading order QCD predictions for W-boson production in association with two photons at the Large Ha…
