v72 v73 25 25 As in the SM, left fermions compose ''SU(2)_L'' doublets. Right charged leptons are accommodated in ''SU(2)_R'' doublets with corresponding extra particles (scotinos) and right upquarks in ''SU(2)_R'' doublets with corresponding extra downtype exotic quarks. Right neutrinos and downquarks are ''SU(2)_L,R'' singlets. The Higgs sector composes of an ''SU(2)_L''doublet, an ''SU(2)_R''doublet and a bidoublet. The physical gauge sector of the model contains the electroweak gauge bosons (photon, ''W'' and ''Z'' bosons) and two extra gauge bosons (''W' '' and ''Z' '') correspond to the ''SU(2)_R'' group. 26 26 27 The leftright symmetry is broken to the SM SU(2)_L×U(1)_Y, Y being the hypercharge, by the SU(2)_Rdoublet vev, then the electroweak symmetry is broken to the U(1)_em through the bidoublet and the SU(2)_Ldoublet vevs. Accordingly, all ferminos and gauge bosons (except of course photon) become massive via Higgs mechanism.27 The leftright 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)_em'' through the bidoublet and the ''SU(2)_L''doublet vevs. Accordingly, all ferminos and gauge bosons (except of course photon) become massive via Higgs mechanism. 28 28 29 29 Dirac (massive) neutrinos are considered with the mixing MNS matrix implemented with the normal hierarchy. Three mixed generations of quarks are considered and hence the general case of the CKM matrix is implemented. In addition, it was considered that the leftright symmetry is manifest, that is the left and right MNS and CKM mixing matrices are coincident. However, this can be generalized directly. 30 30 31 The model contains ten physical Higgs bosons: four neutral CPeven higgs bosons, one (the lightest) of which is fixed to have a mass mh=125 GeV. Four charged Higgs bosons and two CPodd pseudoscalar Higgs bosons. The mass spectrum is calculated and the rotation matrices are implemented analytically.31 The model contains ten physical Higgs bosons: four neutral ''CP''even higgs bosons, one (the lightest) of which is fixed to have a mass ''mh''=125 GeV. Four charged Higgs bosons and two CPodd pseudoscalar Higgs bosons. The mass spectrum is calculated and the rotation matrices are implemented analytically. 32 32 33 33 Minimization conditions and spectrum relations are all used to express the whole model parameters and spectra in terms of only five independent (external) parameters: tanbeta,lambda_2,lambda_3,alpha_1,alpha_2. As in any twoHiggs doublet model, e.g., MSSM, tanbeta is the ratio between two vevs. The parameters lambda_2,lambda_3,alpha_1,alpha_2 are dimensionless potential parameters. The charged Higgs masses are implemented as external parameters.
