SINGLE PRODUCTION OF FOURTH FAMILY SNEUTRINO VIA RPV COUPLINGS AT LINEAR COLLIDERS

Abstract

The single production of fourth family sneutrino [Formula: see text] via R-parity violating interactions in electron–positron collisions has been investigated. We study the decays of [Formula: see text] into different flavor dilepton e±μ∓ via R-parity violation. It is shown that R-parity violating couplings (λ411, λ412) 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.
