A study of single sneutrino production in association with fermion pairs at polarised photon colliders

Abstract

We investigate single sneutrino production in the context of R-parity-violating Supersymmetry at future $\gamma \gamma$ linear colliders. The sneutrino is produced in association with fermion pairs and it is shown that its decays into two further fermions will lead to a clean signal. We also discuss possible backgrounds and the effects of beam polarisation.
