Abstract
We report on a search for R-parity breaking effects due to supersymmet ric tau-sneutrino exchange in the reactions e(+)e(-) --> e(+)e(-) and e(+)e(-) --> mu(+)mu(-) at centre-of-mass energies from 91 GeV to 172 GeV, using the L3 detector at LEP. No evidence for deviations from the Standard Model expectations of the measured cross sections and forwar d-backward asymmetries for these reactions is found. Upper Limits for the couplings lambda(131) and lambda(232), for sneutrino masses up to m(<(nu)over bar>tau) less than or equal to 190GeV are determined from an analysis of the expected effects due to tau sneutrino exchange.
