Bilinear R-parity Violation and ${\tau }^{\mp }{\tilde{\kappa }}^{\pm }$ mixing production in e^+ e^- colliders

Abstract

A R-parity breaking SUSY model characterized by an effective bilinear violation with only $\tau$-lepton number breaking in the superpotential is outlined. The CP-odd Higgs boson masses and those of charged Higgs bosons are discussed. In the model, several interesting mass mixings else such as the mixing between $\tau$ lepton and charginos etc in the model are discussed too. Being one of example, we have computed the mixing production $e^{+}{e}^{-}\to {\tau }^{\mp }{\tilde{\kappa }}_i^{\pm }(i=1,2)$ in e^+ e^- colliders, where ${\tau }^{\mp },{\tilde{\kappa }}_i^{\pm }(i=1,2)$ denote the physical $\tau$ lepton and charginos.
