Abstract

We show that an intermediate scale supersymmetric left-right seesaw scenario with automatic R-parity conservation can cure the problem of tachyonic slepton masses that arise when supersymmetry is broken by anomaly mediation, while preserving ultraviolet insensitivity. The reason for this is the existence of light B\ensuremath-L=2 Higgses with Yukawa couplings to the charged leptons. We find these theories to have distinct predictions compared to the usual mSUGRA and gauge mediated models as well as the minimal anomaly mediated supersymmetry breaking models. Such predictions include a condensed gaugino mass spectrum and possibly a correspondingly condensed sfermion spectrum.
