Single Production of Fourth Family Sneutrino via RPV Couplings at Linear Colliders

Abstract

The single production of fourth family sneutrino ${\tilde{\nu }}_4$ via R-parity violating interactions in electron-positron collisions has been investigated. We study the decays of ${\tilde{\nu }}_4$ into different flavor dilepton $e^{\pm }{\mu }^{\mp }$ via R-parity violation. It is shown that R-parity violating couplings $({\lambda }_{411},{\lambda }_{412})$ down to 0.001 will be reachable at future linear colliders which would provide better accuracy comparing to the indirect measurements as complementary to the LHC results.
