Probing the supersymmetric type III seesaw: LFV at low-energies and at the LHC

TL;DR

This paper investigates a supersymmetric type III seesaw model embedded in SU(5), highlighting its distinctive lepton flavor violation signals at low energies and the LHC, which could test and potentially falsify the model.

Contribution

It analyzes the phenomenological constraints of a supersymmetric type III seesaw embedded in SU(5) and predicts characteristic LFV signals accessible at current experiments.

Findings

Stringent parameter space constraints due to phenomenology

Distinctive low-energy LFV signals predicted

Potential for model falsification through LHC observations

Abstract

We consider a supersymmetric type III seesaw, where the additional heavy states are embedded into complete SU(5) representations to preserve gauge coupling unification. Complying with phenomenological and experimental constraints strongly tightens the viable parameter space of the model. In particular, one expects very characteristic signals of lepton flavour violation both at low-energies and at the LHC, which offer the possibility of falsifying the model.
