Sterile neutrinos in a left-right mirror model
Keywords:Seesaw approximation, neutrino mass matrix, diagonalization, mirror model
In this work we investigate the possibility that one neutrino mirror plays the role of a sterile neutrinos with mass on the scale of a few eV ′ s, that is, mˆ 1 ∼ O(1 eV ). We consider the extension of the Standard Model with gauge symmetry SU(2)L ⊗ SU(2)R ⊗ U(1)Y ′ and additional exotic fermions known as mirror fermions. A double application of the seesaw type I approximation to the most general Majorana-type neutrino mass matrix and diagonalization is performed to study neutrino masses and mixing.
