Two-loop QED and QCD corrections to massless fermion-boson scattering
C. Anastasiou, E. W. N. Glover, M. E. Tejeda-Yeomans
We present the NNLO QCD virtual corrections for qurak-antiquark -> gluon photon, quark-antiquark -> photon photon and the NNLO QED virtual corrections for electron positron -> phot…

One-loop QCD corrections to quark scattering at NNLO
C. Anastasiou, E. W. N. Glover, C. Oleari +1
We present the O(as^4) virtual QCD corrections to unlike-quark and like-quark scattering due to the interference of one-loop amplitudes with one-loop amplitudes. The structure of t…

The two-loop scalar and tensor pentabox graph with light-like legs
C. Anastasiou, E. W. N. Glover, C. Oleari
We study the scalar and tensor integrals associated with the pentabox topology: the class of two-loop box integrals with seven propagators - five in one loop and three in the other…
