Abstract

The minimal model \(SU{{(2)}_{L}} \times SU{{(2)}_{R}} \times U(1)\) with the left-right symmetry at an energy scale of the order of 10 TeV is considered. A three-stage scheme of symmetry breaking of the model up to the standard gauge group is considered, and phenomenologically satisfactory parametric scenarios for the mass spectrum of additional gauge bosons and Higgs bosons are identified. The model contains stable neutral fermions—candidates for the role of dark matter. Parametric scenarios of the Higgs sector of the model have been obtained, which can be consistent with the main phenomenological limitations of experiments on colliders and the main cosmological observables.
