- 331 model
In
particle physics , the 331 model is an extension of theelectroweak gauge symmetry from to with and the hypercharge and the electric charge where T3 and T8 are theGell-Mann matrices of SU(3)L and β and I are parameters of the model. The name 331 comes from the full gauge symmetry group . The 331 model offers an explanation of why there must exist three families of quarks and leptons, a fact which isput in "by hand" in theStandard Model .The minimal 331 model predicts singly- and doubly- charged spin-one bosons,
bilepton s, which could show upin electron-electron scattering when it is studied at TeV energy scales and may also be producedin multi TeV proton-proton scattering at theLarge Hadron Collider as early as 2008.References
