Abstract
- A search for single electrons produced by the decay of singly produced supersymmetric electrons (e-italic-tilde) or W's (W-italic-tilde) within the MAC detector at the SLAC storage ring PEP has been performed in e/sup +/e/sup -/ annihilations at ..sqrt..s = 29 GeV. No evidence of supersymmetric-particle production is observed in a data sample with an integrated luminosity of 206 pb/sup -1/. Limits on possible masses of supersymmetric electrons and photons (gamma-tilde) are presented. The e-italic-tilde mass limit is m/sub e-italic-tilde/>24.5 GeV/c/sup 2/ at the 90% confidence level if m/sub e-italic-tilde//sub >//sub L//sub =/ = m/sub e-tilde//sub =/ and m/sub gamma-tilde/ = 0. If m/sub e-italic-tilde//sub >//sub L//sub =/>>m/sub e-tilde//sub =/, the corresponding limit is m/sub e-italic-tilde//sub >//sub R//sub =/>23.3 GeV/c/sup 2/. Limits on possible masses of supersymmetric W's and neutrino's (nu-tilde) are also presented. The W-italic-tilde mass limit is m/sub W-italic-tilde/>22.0 GeV/c/sup 2/ at the 90% confidence level if m/sub nu-tilde/ = 0.
