Dark matter mixing within the seesaw type II mechanism in the left-right symmetric model
Abstract
The seesaw type II mechanism is considered within the framework of a left-right chiral model with a gauge group SU(2)L× SU(2)R× U(1), the lepton sector of which includes three generations of heavy Majorana neutrinos. The dependence of the mixing parameters of the lightest sterile neutrino as a dark matter particle on the scales of left-right symmetry breaking in the case of direct and inverse hierarchies of active neutrino masses is analyzed.
