| contents | We consider models with broken $μ$-$τ$ permutation symmetry through higher dimensional operators
renormalizing the lepton kinetic terms in the action. We study
the consequences on the structure of the neutrino mass matrix and find in particular that the allowed region for the lightest
mass in the normal hierarchy plotted as a function of the atmospheric mixing element
$|V_{\mu3}|$ is very restricted with the atmospheric mixing angle $θ_{23}$ to lie
in the second octant. On the other hand, the corresponding allowed region in the inverted hierarchy regime
is less restrictive. |
