Lepton-pair scattering with an off-shell and an on-shell photon at two loops in massless QED
Abstract We compute the two-loop QED helicity amplitudes for the scattering of a lepton pair with an off-shell and an on-shell photon, 0 → ℓ ℓ ¯ γγ $$ \ell \overline{\ell}\gamma \gamma $$ *, using the approximation of massless leptons. We express all master integrals relevant for the scattering of f...
