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

Understand

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.
