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

    2727The 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.
