Potential of a linear collider for lepton flavour violation studies in the susy seesaw

We study the potential of an e±e− Linear Collider for charged lepton flavour violation studies in a supersymmetric framework where neutrino masses and mixings are explained by a type-I seesaw. Focusing on e-μ flavour transitions, we evaluate the background from standard model and supersymmetric charged currents to the eμ + signal. We study the energy dependence of both signal and background, and the effect of beam polarisation in increasing the signal over background significance. Finally, we consider the μ−μ− + final state in e−e− collisions that, despite being signal suppressed by requiring two e-μ flavour transitions, is found to be a clear signature of charged lepton flavour violation due to a very reduced standard model background. This contribution summarises part of the work done in [1].
