Abstract
Depending on their masses, supersymmetric particles can affect various measurements in Z decay. Among these are the total width (or conseque nt extracted value of alpha(s)), enhancement or suppression of various flavors, and left-right and forward-backward asymmetries. The latter depend on squark mass splittings and are, therefore, a possible test o f the supergravity related predictions. We calculate leading order cor rections for these quantities considering in particular the case of li ght photino and gluino where the SUSY effects are enhanced. In this li mit the effect on alpha(s) is appreciable, the effect on R-b is small, and the effect on the asymmetries is extremely small.
