Two-loop QCD amplitudes for t t ¯ γ $$ t\overline{t}\gamma $$ production at hadron colliders
Abstract The associated production of a photon and a top-antitop quark pair t t ¯ γ $$ \left(t\overline{t}\gamma \right) $$ is important for measuring the top-quark charge and probing the top-photon interaction, and it requires improved theoretical predictions. We focus on the calculation of two-loo...
