Search for supersymmetric particles at LEP2 with the L3 detector

The searches for supersymmetric particles with the L3 detector at LEP2 are described. Using data collected in 1996 at center-of-mass energies of 161 and 172 GeV with integrated luminosities of 10.7 and 10.0 pb/sup -1/, respectively, sleptons, charginos and neutralinos have been searched for. A search for single and multiphoton events has been performed. Preliminary results using events collected in 1997 at center-of-mass energy of 183 GeV are also presented. (5 refs) .
