The singular behavior of one-loop massive QCD amplitudes with one external soft gluon
Proceedings of "Loops and Legs in Quantum Field Theory " 11th DESY Workshop on Elementary Particle Physics — PoS(LL2012)
In this talk, we present the calculation of the one-loop correction to the soft-gluon current in the case of massive fermions, which describes the singular behaviour of massive one-loop amplitudes when one of the external gluons becomes soft. This current is process independent and can be used in the context of numerical evaluations of massive observables to next-to-next-to leading order (NNLO) at hadron colliders.doi:10.22323/1.151.0060 fatcat:3dxz6ttjgrdrndjadddasbi34m
