Large lepton flavor violating signals in supersymmetric particle decays at future e+e− colliders

We study lepton flavor violating signals at a future ${e}^{+}{e}^{\ensuremath{-}}$ linear collider within the general minimal supersymmetric standard model (MSSM), allowing for the most general flavor structure. There exists a large region in parameter space with large signals being consistent with present experimental bounds on rare lepton decays. We include all possible signals from slepton and sneutrino production and their decays as well as from neutralino and chargino decays. We also consider the background from the standard model and the MSSM. We find that in general the signature $e\ensuremath{\tau}{E}_{T}$ is the most pronounced one.
