A Search for Pair Production of the LSP ??~ at the CLIC via RPV Decays

Abstract

The pair production of tau sneutrinos at the Compact Linear Collider (CLIC) has been investigated. We assume that tau sneutrino is the lightest supersymmetric particle and decays into e mu pair via R-parity violating interactions. Background less subprocess e(-) e(+) -> (v) over tilde (tau)(v) over tilde (tau) -> mu(+) mu(+) e(-) e(-) (mu(-) mu(+) e(+) e(+)) is analyzed in details. Achievable limits on Br ((v) over tilde (tau) -> mu e) are obtained depending on (v) over tilde (tau) mass. It is shown that CLIC with root S = 0.5 TeV and L-int = 2.3 fb(-1) will give opportunity to discover (v) over tilde (tau) if its mass is below 234 GeV. The CLIC with, root S = 3 TeV and L-int = 5.9 fb(-1) will enlarge the discovery region up to M-(v) over tilde tau = 1030 GeV. DOI:10.5506/APhysPolB.44.195
