v85 v86 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 ''SU(2)_L×SU(2)_R×U(1)_BL'' 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 electroweak symmetry is broken down 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.27 The electroweak leftright symmetry ''SU(2)_L×SU(2)_R×U(1)_BL'' 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 electroweak symmetry is broken down 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. 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 leftright symmetry is manifest, that is the left and right MNS and CKM mixing matrices are coincident. However, this can be generalized directly.
