Abstract
We calculate the supersymmetric O((alpha(s)) QCD corrections to the cr oss section e(+)e(-) --> (q) over tilde(i) (q) over tilde and over bar (j) (i, j = 1,2) within the Minimal Supersymmetric Standard Model. We pay particular attention to the case of the left-right squark mixing a nd to the renormalization of the mixing angle. The corrections due to gluino exchange turn out to be smaller than those due to gluon exchang e, but they can be significant at higher energies, even for a gluino m ass of a few hundred GeV.
