A Search for pair production of the LSP $\tilde{ν_τ}$ 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 $e{}^{-}e^{+}\rightarrow\tildeν\bar{\tildeν}\rightarrowμ^{+}μ^{+}e^{-}e^{-}(μ^{-}μ^{-}e^{+}e^{+})$ is analyzed in details. Achievable limits on $Br\,(\tildeν_τ\rightarrowμe)$ at $3σ$ and $5σ$ CL are obtained depending on $\tilde{ν_τ}$ mass.
