Minimal Seesaw as an Ultraviolet Insensitive Cure for the Problems of Anomaly Mediation

Understand

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 arises when supersymmetry is broken by anomaly mediation, while preserving ultraviolet insensitivity.

• The reason for this is the existence of light B - 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 AMSB models.
• Such predictions include a condensed gaugino mass spectrum and possibly a correspondingly condensed sfermion spectrum.
