| 33 | 33 | The left-right symmetry is broken to the SM SU(2)_L×U(1)_Y, Y being the hypercharge, by the SU(2)_R-doublet vev, then the electroweak symmetry is broken to the U(1) electromagnetism through the bidoublet and the SU(2)_R-doublet vevs. Accordingly, all ferminos and gauge bosons (except of course photon) become massive through the so-called Higgs mechanism. The model contains ten physical Higgs bosons: four neutral CP-even higgs bosons, the lightest one of which is fixed to have a mass mh=125 GeV. Two charged gauge bosons and two CP-odd pseudoscalar Higgs bosons. The mass spectrum is calculated and the rotation matrices are implemented analytically. All model parameters and spectra are expressed in terms of only five independent (external) parameters: tanbeta,lambda_2,lambda_3,alpha_1,alpha_2. As in any two-Higgs doublet model, e.g., tanbeta is the ratio between two vevs. The parameters lambda_2,lambda_3,alpha_1,alpha_2 are dimensionless potential parameters. |
