Descripción
In this talk I plan to introduce the Four-Dimensional-Formulation (FDF) regularisation scheme proposed in arXiv:1404.4783 [hep-ph], which allows a four-dimensional representation of the d-dimensional particles propagating in the loop. Within FDF, I present the computation of one-loop QCD corrections of the processes gg>>gggg and gg>>Hggg (in the heavy top limit).
On the other hand, I show the extension of BCJ identities in d-dimensions and their application to compute efficiently one-loop amplitudes.
