    2222As any other left-right symmetric model, the Alternative Left-Right Symmetric Model (ALRM) is a QFT which is gauged by the Left-Right gauge symmetry group ''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.

    24 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.

    2626The 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 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.
