A search for scalar leptons properties at TeV energy colliders

In this study, the pair production of scalar leptons and tau sneutrinos at the Compact Linear Collider (CLIC) has been investigated. We assume that tau sneutrino is the lightest supersymetric particle and decays into elektron muon pair via R parity violating (RPV) interactions. The production cross sections of tau sneutrinos and corresponding number of events per year are computed at the CLIC energy values. If R parity is violated the backgroundless process under consideration is very important. Achievable limits on at 3(sigma)and 5(sigma) CL are obtained depending on tau scaler neutrino mass.
