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 → ℓℓ¯γγ*, using the approximation of massless leptons. We express all master integrals relevant for the scattering of four... Read More about Lepton-pair scattering with an off-shell and an on-shell photon at two loops in massless QED.
