SUPERSYMMETRIC QCD CORRECTIONS TO THE W-BOSON WIDTH

We calculate the one-loop supersymmetric QCD corrections to the width of the W-boson. We find that these are of order similar to alpha(s)/pi 1/20 M(W)(2)/M(S)(2) Gamma(<u(d)over bar>) where MS is the supersymme try breaking scale and Gamma(<u(d)over bar>) the tree level hadronic w idth for W+ --> (<u(d)over bar>). Due to the appearance of the suppres sion factor similar to 1/20 these are at least two orders of magnitude smaller than the standard QCD corrections similar to alpha(1)/pi Gamm a(<u(d)over bar>) and hence of the order of the two-loop electroweak e ffects, Therefore supersymmetric QCD corrections will only be of relev ance once experiments reach that level of accuracy.
