Single chargino production with R-parity lepton number violation in photon-photon collisions

We examine the process gamma gamma --> <(<chi>)over tilde>(+)tau (-) at pho ton-photon collider in the minimal supersymmetric standard model with R-par ity violation, where all the one-loop diagrams are considered. We mainly di scuss the effects of bilinear breaking terms, and conclude that their contr ibutions may be important compared with trilinear terms. Our results show t hat the events of this process could be detectable at photon-photon collide rs, if the values of the parameters are favorable.
