Two-loop integrals for $t\bar{t}\gamma$ production at hadron colliders in the leading-colour approximation

We complete the calculation of the two-loop Feynman integrals required for the next-to-next-to-leading order QCD corrections to on-shell top--antitop production in association with a photon at hadron colliders, in the leading-colour approximation. The same integrals also enter the subleading-colour corrections to top--...
