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

C. H. Chang, T. F. Feng, L. Y. Shang

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 masse…
