Minimal Flavor Violation, Seesaw, and R-parity

TL;DR

This paper extends the Minimal Flavor Violation hypothesis to R-parity violating MSSM with a seesaw mechanism, showing it suppresses dangerous couplings and remains consistent with experimental bounds, offering an alternative to R-parity.

Contribution

It demonstrates that MFV can be applied to R-parity violating MSSM with a seesaw, providing a viable suppression mechanism for dangerous couplings.

Findings

MFV suppresses lepton and baryon-number violating couplings effectively.

Proton decay bounds are satisfied under MFV in this framework.

Predicts sizeable baryon-number violation in specific collider channels.

Abstract

The Minimal Flavor Violation hypothesis (MFV) is extended to the R-parity violating MSSM, supplemented with a simple seesaw mechanism. The requirement of MFV is shown to suppress lepton and baryon-number violating couplings sufficiently to pass all experimental bounds, in particular those for proton decay, and is thus a viable alternative to R-parity. The phenomenological consequences for FCNC, LFV and colliders are briefly discussed. Typically, MFV predicts sizeable baryon-number violation in some characteristic channels, like single stop resonant production.
