Generations of Quarks and Leptons from Noncompact Horizontal Symmetry
نویسنده
چکیده
The three chiral generations of quarks and leptons may be generated through a spontaneous breakdown of the noncompact horizontal gauge symmetry GH which governs, together with the standard gauge symmetry SU(3)× SU(2)× U(1), the world in a vectorlike manner. In a framework of supersymmetric theory, the simplest choice GH = SU(1, 1) works quite well for this scenario in which quarks, leptons and Higgses belong to infinite dimensional unitary representation of SU(1, 1). The relevance of the scenario to the hierarchical structure of their Yukawa coupling matrices are discussed. §

Grand Unification with Anomalous U(1) Symmetry and Non-abelian Horizontal Symmetry
Non-abelian horizontal symmetry has been considered to solve potentially SUSY flavor problem, but simple models are suffering from various problems. In this talk, we point out that (anomalous) U(1)A gauge symmetry solves all the problems in a natural way, especially, in the E6 grand unified theories. Combining the GUT scenario with anomalous U(1)A gauge symmetry, in which doublet-triplet splitt...
متن کاملHorizontal symmetry and mass of the t quark
The idea of unifying electronic and muonic matter by adding the horizontal symmetry SU+(2)" to the weak and eiectromagnetic group SU(2) &&U(l)' has recently been suggested. As a consequence of gauging the symmetry, the conservation of muon number is violated. Exchange of extra gauge bosons S; (a =1-3) also induces a superweak type of CP nonconservation. " From the data on CP violation in KL-2n ...

The new mechanism for the generation of the chiral generations is proposed based on the SU (1, 1) horizontal gauge symmetry. The appearance of the chiral generations is controlled by the coupling constants of the model. This is crucial in the grand unification scheme. The resulting chiral generations naturally acquire the hierarchal Yukawa coupling matrices. Propriety of the model to the observ...
