“…This group named as SU (2) R will assign the chiral right fermion fields in representation of doublets while the chiral left fermion fields will be assigned as singlets, that is, an inverse assignment for the chiral projections in SU (2) L . We consider the LR model which includes the same amount of left fermions as right fermions [3][4][5]. New fermions are included such that the right (left) projections are doublets (singlets) under SU (2) R .…”

We discussed the feasibility of including dark matter in the Left-Right Mirror Model with an additional discrete Z2 symmetry. The Z2 symmetry helps to prevent any decay of the possible dark matter candidate, that is, guarantees the stability of the dark matter. The dark matter candidate is proposed as the lightest mirror neutrino. This Z2 discrete symmetry not only guarantees the stability of the dark matter but also controls the free parameters of the model such that they are significantly reduced. Then, mass spectrum of neutrinos is also discussed in two possible scenarios obtained by assigning charge under Z2 symmetry. For one of the scenarios we obtain the relic density for the dark matter candidate and the spin independent scattering cross section between dark matter and proton (neutron).

“…In the Neutrino-4 experiment the effect of oscillations of reactor antineutrinos into a sterile neutrino was observed [1,2]. Here, we study neutrino masses within the context of the "Left Right Mirror Model" (LRMM) [3][4][5][6]. Applying a double seesaw approximation to the most general Majoranatype neutrino mass matrix, we perform an approximate analytical diagonalization, where one of the mirror neutrinos may get a mass of a few eV's.…”

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.
