Two-loop Calculations in the MSSM with FeynArts
S. Heinemeyer
Abstract
Recent electroweak two-loop corrections in the Minimal Supersymmetric Standard Model (MSSM) are reviewed. They have been obtained with the help of the programs FeynArts and TwoCalc, making use of the recently completed MSSM model file for FeynArts. Short examples of how to use the two codes together with the analytic result for the O(Gf2 mt4) corrections to the ρ-parameter in the MSSM are presented.
