Supersymmetry Breaking by the Right-Handed Tau Neutrino

Abstract

We describe supersymmetry breaking by the F-term of a heavy right-handed tau neutrino with a VEV. Due to the the tau neutrino Yukawa coupling, the neutralino, chargino and scalar mass matrices and the weak currents are modified. In addition, there are new cubic and quartic scalar and trilinear R parity violating interactions. For large $\tan \beta$ these effects may be quite large. The scenario requires low energy supersymmetry breaking with generic values of $F\sim 10^{10}$~GeV.
