Abstract

Searching for the supersymmetric (scalar) partners of charged leptons and quarks at Z0 factories will only be relatively easy in the favorable case of pair decay, when mf<MZ2. Using the scalar electron as an illustration, we calculate the rate for the decays Z0→e±e1,2γ, relevant to the a priori equally likely case of larger scalar-lepton masses MZ2ml<MZ- mγ. We conclude that for photino masses under 10 GeV, scalar electrons (or other scalar leptons) of mass up to 55 GeV may be detected in such Z0 decays. We also comment on single-scalar-quark decays of the Z0, with the emission of either a photino or a gluino.
