QCD Corrections to Electroweak Precision Observables in SUSY Theories
Abstract
Description
The two-loop QCD corrections to the $ρ$ 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 $Δr$ are presented and compared with the leading contribution entering via the $ρ$ parameter.
