Abstract

We list all possible R2 Feynman rules needed in NLO computations involving couplings of Higgs and gluons mediated by an infinitely heavy top loop. They provide the rational contribution generated by the (d-4)-dimensional part of the amplitude, paving the way for four-dimensional automatic NLO methods in Higgs phenomenology.
