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 161GeV and 172GeV 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.
