Abstract

We consider one-loop corrections to partial widths of the Z induced by supersymmetric Yukawa interactions that violate R-parity. The precise experimental values of the leptonic Z partial widths bound these Yukawa couplings, with the most interesting constraints being those on couplings involving τ, since previous constraints on them were very mild.
