A search for the supersymmetric chargino in e +e- annihilation at PETRA
Abstract
A search has been made for the chargino, the supersymmetric partner of the W ± (or the partner of the charged Higgs bosons), in e + e - annihilation at PETRA using the JADE detector. The chargino decay modes investigated areltilde v, lbar vtilde γ , q_1 bar q_2 tilde γ andq_1 bar q_2 tilde g (with subsequent gluino decaytilde g to qbar qtilde γ). No evidence for such events has been observed. The 95% C.L. lower limit for the chargino mass is typically 22.5 GeV, depending only slightly on the masses of other supersymmetric particles. If the chargino is stable, the lower mass limit is 21.1 GeV (95% C.L.).
