Abstract 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 Model parameter space as well as new lower limits on masses are derived.
