    2626The electroweak left-right symmetry ''SU(2),,L,,×SU(2),,R,,×U(1),,B-L,,'' is spontaneously broken down to the SM electroweak symmetry ''SU(2),,L,,×U(1),,Y,,'', ''Y'' being the hypercharge, by the ''SU(2),,R,,''-doublet vev, then the SM electroweak symmetry is spontaneously broken down to the ''U(1),,em,,'' through the bidoublet and the ''SU(2),,L,,''-doublet vevs. Accordingly, all fermions and gauge bosons (except of course photon) become massive via Higgs mechanism. The physical gauge sector of the model contains the electroweak gauge bosons (photon, ''W'' and ''Z'' bosons, whose masses were fixed by the experimental SM values) in addition to two extra gauge bosons (''W' '' and ''Z' '') correspond to the ''SU(2),,R,,'' group, analogous to those of the ''SU(2),,L,,'' group. Also the Weinberg angle is fixed here as an input parameter by its experimental value.

    28 Dirac (massive) neutrinos are considered with the mixing MNS matrix implemented in the normal hierarchy. The case of Majorana neutrinos is considered in many other models' files and any type of seesaw mechanisms can be brought to be implemented here easily. Three mixed generations of quarks are considered and hence the general case of the CKM matrix is implemented. In addition, the generic case of nonmanifest left-right symmetry is considered, that is the left and right gauge couplings gL,gR, quark mixing matrices CKM,CKMR and lepton mixing matrices MNS,MNSR are NOT in general coincident.

    3030The model contains ten physical Higgs bosons: four neutral ''CP''-even higgs bosons, one (the lightest) of which is considered to be the SM-like one with mass fixed to have the value ''mh''=125 GeV. Four charged Higgs bosons and two ''CP''-odd pseudoscalar Higgs bosons. The mass spectra are calculated and the rotation matrices are implemented analytically.
