The effect of R parity violating couplings on e-e--> eL eR
Uma Mahanta
Abstract
In this work we study the effect of R parity breaking couplings on the process e-e--> eL eR. 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 [λ211+λ311]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 σLR-σRR which reduces the MSSM background.
