    2323As any other left-right symmetric model, ALRM is a QFT gauged by ''SU(3)_C×SU(2)_L×SU(2)_R×U(1)_B-L''. The latter ''B'' and ''L'' being the baryon and lepton numbers. An extra discrete symmetry ''S'' is imposed to distinguish between Higgs fields and their dual fields and hence their interactions.

    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 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) in addition to two extra gauge bosons (''W' '' and ''Z' '') correspond to the ''SU(2)_R'' group.

    27 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 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.

    2929Dirac (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.
