1202.4234 (Yoni BenTov et al.)

Lepton Private Higgs and the discrete group Σ(81)    [PDF]

Yoni BenTov, A. Zee
We use the discrete group \Sigma(81) = (Z_3 x Z_3 x Z_3)\rx Z_3 to suggest a
relation among the off-diagonal entries of the neutrino mass matrix, as well as
to explain 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.
The appendix is devoted to the group theory of \Sigma(81).
