Two-loop leading-color helicity amplitudes for three-photon production at the LHC
We calculate all planar contributions to the two-loop massless helicity amplitudes for the process qq¯¯ → γγγ. The results are presented in fully analytic form in terms of the functional basis proposed recently by Chicherin and Sotnikov. With this publication we provide the two-loop contributions al...
