Abstract

We report on a search for R-parity breaking effects due to supersymmetric tau-sneutrino exchange in the reactions e⁺e^-→ e⁺e^- and e⁺e^-→ μ⁺μ^- 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 forward-backward asymmetries for these reactions is found. Upper limits for the couplings λ₁₃₁ and λ₂₃₂ for sneutrino masses up to m_ṽτ ≤ 19OGeV are determined from an analysis of the expected effects due to tau sneutrino exchange.

N2 - We report on a search for R-parity breaking effects due to supersymmetric tau-sneutrino exchange in the reactions e+e-→ e+e- and e+e-→ μ+μ- 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 forward-backward asymmetries for these reactions is found. Upper limits for the couplings λ131 and λ232 for sneutrino masses up to mṽτ ≤ 19OGeV are determined from an analysis of the expected effects due to tau sneutrino exchange.
