Single sneutrino production in γγ collisions

We study the single production of sneutrinos with two leptons (or jets) via γγ collision in an R-parity (Rp) violating supersymmetric model. The subsequent decays of the sneutrino are also considered. The single production of sneutrinos may provide a significant test of supersymmetry and Rp-violation with flavour conserving and flavour changing final states. If such processes coming from Rp violation are not detected, the parameter space of the model will be strongly constrained at the future linear collider.
