Abstract
We present a detailed examination of electron spectra from collider events which are characteristic of the decay of , the superpartner of the boson. The events studied are those with a single electron and no associated charged particles or jets. Such events can arise from the sequential decay , where denotes a photino. For electron energies less than 30 GeV, the background from direct--decay electrons is manageably small. The other source of electrons in this energy range—sequential decays of the form , where is a heavy lepton or —is also treated. We find that decay provides a substantial excess of single electrons if the mass is less than 50 GeV. It does not seem possible, however, to distinguish between a and a heavy lepton of the same mass on the basis of these spectra.
