摘要：

The partial widths are determined for squark decays to gluinos and quarks, and gluino decays to squarks and quarks, respectively. The widths are calculated including one-loop SUSY-QCD corrections. The corrections amount +30% to +50% for squark decays and -10% to +10% for gluino decays. We have derived the results in the <(DR)over bar> and <(MS)over bar> renormalization schemes, and we have demonstrated explicitly that the one-loop effective qqg and <q(qg)over tilde> couplings are equal in the limit of exact supersymmetry.
