FeynArts model file for MSSM transition counterterms from DREG to DRED

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)

Abstract
The FeynArts model file MSSMdreg2dred implements MSSM transition counterterms which can convert one-loop Green functions from dimensional regularization to dimensional reduction. They correspond to a slight extension of the well-known Martin/Vaughn counterterms, specialized to the MSSM, and can serve also as supersymmetry-restoring counterterms. The paper provides full analytic results for the counterterms and gives one- and two-loop usage examples. The model file can simplify combining MS-parton.....

Title of program: MSSMdreg2dred.mod
Catalogue Id: AEKR_v1_0

Nature of problem
The computation of one-loop Feynman diagrams in the minimal supersymmetric standard model (MSSM) requires regularization. Two schemes, dimensional regularization and dimensional reduction are both common but have different pros and cons. In order to combine the advantages of both schemes one would like to easily convert existing results from one scheme into the other.
