Three-loop vertex corrections
Published 18 Jan 2010 in hep-ph | (1001.3124v1)
Abstract: We describe recent evaluations of three-loop vertex corrections which have been performed in the context of different physical applications: the massless quark and gluon form factor, the vector current matching coefficient between QCD and NRQCD, and the virtual corrections of the gluon-Higgs coupling with finite top quark mass.
