A Search for pair production of the LSP $\widetilde{{\nu }_{\tau }}$ at the CLIC via RPV Decays

Abstract

In this work we consider pair production of LSP tau-sneutrinos at the Compact Lineer Collider. We assume that tau-sneutrinos decays in to e\textmu pair via RPV interactions. Backgroundless subprocess $e{}^{-}{e}^{+}\to \tilde{\nu }\overline{\stackrel{~}{\nu }}\to {\mu }^{+}{\mu }^{+}{e}^{-}{e}^{-}({\mu }^{-}{\mu }^{-}{e}^{+}{e}^{+})$ is analyzed in details. Achievable limits on $Br({\tilde{\nu }}_{\tau }\to \mu e)$ at $3\sigma$ and $5\sigma$ CL are obtained depending on $\widetilde{{\nu }_{\tau }}$ mass.
