摘要
Scalar leptons, charginos and neutralinos, predicted by supersymmetric theories, have been searched for in data samples collected with the L3 detector at centre-of-mass energies of 161 GeV and 172 GeV with integrated luminosities of 10.7 pb(-1) and 10.0 pb(-1) respectively. No evidence for such particles is found. New limits on production cross sections are set, assuming R-parity conservation. New exclusion contours in the Minimal Supersymmetric Standard Mc del parameter space as well as new lower limits on masses are derived.
