Probing neutrino and Higgs sectors in $SU(2)_1 \times SU(2)_2 \times U(1)_Y$ model with lepton-flavor non-universality

Understand

The neutrino and Higgs sectors in the $\mbox{SU(2)}_1 \times \mbox{SU(2)}_2 \times \mbox{U(1)}_Y $ model with lepton-flavor non-universality are discussed.

• We show that active neutrinos can get Majorana masses from radiative corrections, after adding only new singly charged Higgs bosons.
• The mechanism for generation of neutrino masses is the same as in the Zee models.
• This also gives a hint to solving the dark matter problem based on similar ways discussed recently in many radiative neutrino mass models with dark matter.
