Abstract We consider a minimal supersymmetric extension of the standard electroweak model with Dirac neutrino masses. In such a model for a significant region of the parameters the right-handed tau sneutrino is the lightest superparticle and the right-handed charged tau slepton is the next-to-lightest superparticle. Due to the smallness of the neutrino masses the right-handed tau slepton is a long-lived particle that alters the standard signatures used in the search for supersymmetry at supercolliders. The most striking signatures of such a scenario is the existence of highly ionized tracks and an excess of multilepton events that is similar to the phenomenology of gauge-mediated supersymmetry-breaking models.
