    2525As 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 up-quarks in ''SU(2)_R'' doublets with corresponding extra down-type exotic quarks. Right neutrinos and down-quarks 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.

    27 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)_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.

    2929Dirac (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 left-right symmetry is manifest, that is the left and right MNS and CKM mixing matrices are coincident. However, this can be generalized directly.

    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 CP-odd pseudoscalar Higgs bosons. The mass spectrum is calculated and the rotation matrices are implemented analytically.

    3333Minimization 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 two-Higgs 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.
