Single sneutrino production in gamma gamma collisions

We study the single production of sneutrinos with two leptons (or jets) via gamma gamma collision in an R-parity (R-p) violating supersymmetric model. The subsequent decays of the sneutrino, are also considered. The single pr oduction of sneutrinos may provide a significant test of supersymmetry and R-p-violation with flavour conserving and flavour changing final states. If such processes coming from R-P violation are not detected, the parameter s pace of the model will be strongly constrained at the future Linear collide r. (C) 2001 Published by Elsevier Science B.V.
