Abstract
In this work we study the effect of R parity breaking couplings on the process e^-e^-->{\tilde e}_L{\tilde e}_R. We find that an e^-e^- linear collider opearting at a center of mass energy of 500 Gev with a luminosity of 50 fb^{-1} will be able to probe the coupling [\lambda_{211}+\lambda_{311}]^{1/2} down to .045 for a bino mass of 100 Gev and selectron mass of 200 Gev. This would improve the current bound on it by a factor of 3.5. More improved bounds can be obtained from precision measurement of \sigma_{LR}-\sigma_{RR} which reduces the MSSM background.
