Abstract
We present the complete set of Feynman rules producing the rational terms of kind R2 needed to perform any 1-loop calculation in the Electroweak Standard Model. Our results are given both in the ’t Hooft-Veltman and in the Four Dimensional Helicity regularization schemes. We also verified, by using both the ’t Hooft-Feynman gauge and the Background Field Method, a huge set of Ward identities -up to 4-points-for the complete rational part of the Electroweak amplitudes. This provides a stringent check of our results and, as a by-product, an explicit test of the gauge invariance of the Four Dimensional Helicity regularization scheme in the complete Standard Model at 1-loop. The formulae presented in this paper provide the last missing piece for completely automatizing, in the framework of the OPP method, the 1-loop calculations in the SU(3) × SU(2) × U(1) Standard Model.
