The Potential of Leptonic Minimal Flavour Violation

We explore the possibility of spontaneous lepton flavour symmetry breaking in the context of Minimal Flavour Violation and within a minimal and predictive See-Saw model. In this context the Yukawa couplings are the vacuum expectation values of scalar fields transforming under the flavour group. The scalar potential giving rise to the acquisition of the vev of the scalar fields is derived and analyzed. In the minimization the Majorana character of neutrino masses plays a distinctive role, absent for the quark case.
