Automatic evaluation of UV and R 2 terms for beyond the Standard Model Lagrangians: A proof-of-principle

Listed in Teesside University Research Data Repository

Description

Abstract

The computation of renormalized one-loop amplitudes in quantum field theory requires not only the knowledge of the Lagrangian density and the corresponding Feynman rules, but also that of the ultraviolet counterterms. More in general, and depending also on the method used in the actual computation of the one-loop amplitudes, additional interactions might be needed. One example is that of the ^(R2)rational terms in the OPP method.

Title of program: FeynRules-2.1 with NLOCT Catalogue Id: AEDI_v2_1 Nature of problem The new version of FeynRules renormalises and computes with the new NLOCT package the ultraviolet counterterms and the rational R 2 terms induced by one-loop amplitudes. The resulting vertices can be exported in the UFO format to event generators such as MadGraph5_aMC@NLO.
