Enhanced Electroweak Radiative Corrections in SUSY: Gluon-free Observables

Abstract

Large top quark mass is responsible for the enhancement of the oblique radiative corrections in SUSY models. We present the analytical formulas for these corrections to the $W$-boson mass $m_W$ and to $Z$ $l^{+}{l}^{-}$ coupling constants. The comparison with the result of the Standard Model fit is made.
