ALRM
v174 v175 22 22 As any other leftright symmetric model, the Alternative LeftRight Symmetric Model (ALRM) is a QFT which is gauged by the LeftRight gauge symmetry group ''SU(3),,C,,×SU(2),,L,,×SU(2),,R,,×U(1),,BL,,''. 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. 23 23 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 upquarks in ''SU(2),,R,,'' doublets with corresponding extra downtype exotic quarks. Rightneutrinos 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.24 As in the SM, lefthanded fermions compose ''SU(2),,L,,'' doublets. Righthanded charged leptons are accommodated in ''SU(2),,R,,'' doublets with corresponding extra particles (scotinos) and righthanded upquarks in ''SU(2),,R,,'' doublets with corresponding extra downtype exotic quarks. Righthanded 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. 25 25 26 26 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 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.
