    2424As in the SM, left-handed fermions compose ''SU(2),,L,,'' doublets. Right-handed charged leptons form ''SU(2),,R,,'' doublets with corresponding extra particles (scotinos) and right-handed up-quarks form ''SU(2),,R,,'' doublets with corresponding extra down-type exotic quarks. Right-handed 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.

    26 The electroweak left-right symmetry ''SU(2),,L,,×SU(2),,R,,×U(1),,B-L,,'' is 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 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) 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.
     26The 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.

    2828Dirac (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 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, 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.
