Predictions for μ → eγ in Supersymmetry from Nontrivial Quark-Lepton Complementarity and Flavor Symmetry
We compute the effect of nondiagonal neutrino mass in l i → l j γ in Supersymmetry (SUSY) theories with nontrivial quark-lepton complementarity and a flavor symmetry. The correlation matrix V M = U CKM U PMNS is such that its (1,3) entry, as preferred by the present experimental data, is zero. We do...

| Summary: | We compute the effect of nondiagonal neutrino mass in

in Supersymmetry (SUSY) theories with nontrivial quark-lepton complementarity and a flavor symmetry. The correlation matrix

is such that its (1,3) entry, as preferred by the present experimental data, is zero. We do not assume that
V
M
is bimaximal. Quark-lepton complementarity and the flavor symmetry strongly constrain the theory and we obtain a clear prediction for the contribution to

and the

. If the Dirac neutrino Yukawa couplings are degenerate but the low-energy neutrino masses are not degenerate, then the lepton decays are related among them by the

entries. On the other hand, if the Dirac neutrino Yukawa couplings are hierarchical or the low-energy neutrino masses are degenerate, then the prediction for the lepton decays comes from the

hierarchy. |
