Description
The possibility of the lightest sterile neutrino with a mass of about a few keV as warm dark matter (DM) in the framework of the Minimal left-right symmetric model (MLRM) based on the SU(3)cSU(2)LSU(2)R*U(1) gauge group is considered. Only few parameters of the model are free which makes it rather predictable and unambiguous. We thoroughly consider a parametrization in the lepton sector and obtain a general form for mixing matrices and mixing parameters. Cosmological and astrophysical constraints on DM neutrino are analyzed. In the case of the mass of W_R of about 5 TeV, the model phenomenology consistent with current experimental data is considered.
