Abstract:
We embed a (modified) Private Higgs model for leptons into a flavor group \Sigma(81) = (Z_3 x Z_3 x Z_3)\rtimes Z_3. This suggests a relation among the off-diagonal entries of the neutrino mass matrix and explains the muon magnetic moment anomaly, a_\mu^exp-a_\mu^SM ~ 10^{-9}. We predict three new nearly degenerate Higgs doublets with masses of order ~500 GeV to ~ 1 TeV, and three nearly degenerate SM-singlet TeV-scale neutrinos. The largest scale in the model is ~10 TeV, so there is no severe hierarchy problem. We conclude by discussing the possibility of extending the model to the quark sector.
