The Implementation of the Renormalized Complex MSSM in FeynArts and FormCalc

Understand

We describe the implementation of the renormalized complex MSSM (cMSSM) in the diagram generator FeynArts and the calculational tool FormCalc.

• This extension allows to perform UV-finite one-loop calculations of cMSSM processes almost fully automatically.
• The Feynman rules for the cMSSM with counterterms are available as a new model file for FeynArts.
• Also included are default definitions of the renormalization constants; this fixes the renormalization scheme.
