title = "Search for chargino and neutralino production using the OPAL detector at √s = 130-136 GeV at LEP",
abstract = "A search for charginos and neutralinos, predicted by supersymmetric theories, has been performed using a data sample of 2.6 pb-1 at a centre-of-mass energy of √s = 130 GeV and 2.6 pb-1 at 136 GeV collected with the OPAL detector at LEP during November 1995. No candidate events were observed. The 95% C.L. lower limit on the lightest chargino mass in the Minimal Supersymmetric Standard Model is 65.4 GeV if the universal scalar mass m0 is greater than 1 TeV, and 58.7 GeV for the smallest m0 compatible with slepton and sneutrino mass limits obtained at centre-of-mass energies near the Z peak. These limits were obtained under the conditions that the lightest chargino is heavier than the lightest neutralino by more than 10 GeV and tan β is larger than 1.5. The results of a model independent search for charginos and neutralinos are also given.",
