A search for the supersymmetric chargino ine +e annihilation at PETRA

Abstract

A search has been made for the chargino, the supersymmetric partner of theW ± (or the partner of the charged Higgs bosons), ine + e annihilation at PETRA using the JADE detector. The chargino decay modes investigated are\(l\tilde v, l\bar v\tilde \gamma , q_1 \bar q_2 \tilde \gamma\) and\(q_1 \bar q_2 \tilde g\) (with subsequent gluino decay\(\tilde g \to q\bar q\tilde \gamma\)). 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.).

For the analysis of the muonic channel for C.M. energies below 37GeV a reduced data sample corresponding to 37 pb−1 was used since an efficient trigger for such events has been in operation only since 1982. The total luminosity for the analysis of this channel was 53 pb−1 (512-1 up to 46.78 GeV)
