Lepton flavour violation at high energies: The LHC and a Linear Collider

Abstract

We discuss several manifestations of charged lepton flavour violation at high energies. Focusing on a supersymmetric type-I seesaw, considering constrained and semi-constrained supersymmetry breaking scenarios, we analyse different observables, both at the LHC and at a future Linear Collider. We further discuss how the synergy between low- and high-energy observables can shed some light on the underlying mechanism of lepton flavour violation. PACS 14.60.St - Non-standard-model neutrinos.
