Neutrino Masses with Inverse Hierarchy from Broken $L_{e}-L_{\mu}-L_{\tau}$: a Reappraisal
We discuss a class of models of neutrino masses and mixings with inverse hierarchy based on a broken U(1)_F flavour symmetry with charge L_e-L_\mu-L_\tau. The symmetry breaking sector receives separate contributions from flavon vev breaking terms and from soft mass breaking in the right handed Major...
