Mass renormalization in a toy model with spontaneously broken symmetry
W. Grimus, P. O. Ludl, L. Nogués
We discuss renormalization in a toy model with one fermion field and one real scalar field phi, featuring a spontaneously broken discrete symmetry which forbids a fermion mass term…

A complete survey of texture zeros in the lepton mass matrices
Patrick Otto Ludl, Walter Grimus
We perform a systematic and complete analysis of texture zeros in the lepton mass matrices and identify all viable and maximally restrictive cases of pairs (M_\ell, M_D) and (M_\el…

Residual Z2 x Z2 symmetries and lepton mixing
Luis Lavoura, Patrick Otto Ludl
We consider two novel scenarios of residual symmetries of the lepton mass matrices. Firstly we assume a Z2 x Z2 symmetry G_ell for the charged-lepton mass matrix and a Z2 symmetry…
