Bilinear R-parity Violation and $τ^{\mp} \tildeκ^{\pm}$ mixing production in e^+ e^- colliders

Abstract

A R-parity breaking SUSY model characterized by an effective bilinear violation with only $τ$-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 $τ$ lepton and charginos etc in the model are discussed too. Being one of example, we have computed the mixing production $e^{+} e^{-} \to τ^{\mp} \tildeκ^{\pm}_{i} (i=1,2)$ in e^+ e^- colliders, where $τ^{\mp}, \tildeκ^{\pm}_{i}(i=1,2)$ denote the physical $τ$ lepton and charginos.
