An A4 Model for keV-Scale Sterile Neutrino Dark Matter
We develop an A4 × Z4 × Z2 symmetry model of neutrino masses and mixings within the minimal extended seesaw mechanism where three right-handed neutrinos νR1, νR2, and νR3 and a keV-scale singlet sterile neutrino S are added to the Standard Model. This model breaks μ-τ symmetry of the neutrino mass...
