QCD Corrections to Electroweak Precision Observables in SUSY Theories

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

The two-loop QCD corrections to the ρ\rho parameter are derived in the Minimal Supersymmetric Standard Model. They turn out to be sizable and modify the one-loop result by up to 30%. Furthermore exact results for the gluonic corrections to Δr\Delta r are presented and compared with the leading contribution entering via the ρ\rho parameter.
