Antenna subtraction at NNLO for heavy quark pair production at hadron colliders: the non-diagonal channels

Aude Gehrmann-De Ridder, João Pires

We present the calculation involving the $qq$, $q{q}^{\prime }$ and $qg$ partonic channels contributing to heavy-quark pair production at hadron colliders through next-to-next-to-leading orde…
