Production of scalar leptons in W- and Z-boson decay

Alternative decay modes of the W and Z bosons may provide a method either to discover the supersymmetric partners of leptons or to set greatly improved limits on their masses. Details are provided on these methods, and various distributions are shown for separating potential backgrounds. If ppWess is allowed, a clear signal for supersymmetry could be established from future data. In e+e- annihilation a distinctive signature for scalar neutrinos could be jets plus an electron all confined to a single hemisphere (with substantial missing energy). Even more dramatic but rarer would be events with only e++- together in one hemisphere and all other energy missing.
