SUSY model with R-parity violation and long-lived charged slepton
Krasnikov N.V.
We construct a SUSY electroweak model with superweak Я-parity violation. The scale of Д-parity violation in our model is determined by the Majorana mass of the neutrino and is very small, leading to the existence of a long-lived (T > O(10-4) sec) lightest superparticle. If the lightest superparticle is a right-handed charged slept on, as can occur within the gaugino-dominated scenario, then the phenomenology of such a model differs in a drastic way from the standard SUSY phenomenology; in particular, long-lived charged sleptons can form bound states with ordinary matter — quasistable supermatter (SUSY analogs of mu-atoms and muonium). We also discuss possible manifestations of the existence of such a long-lived charged particle at LEP2, TEVATRON and LHC. PACS: 12.60.Jv
