A Model for the Quark Mass and Flavor Mixing Matrices Based on Discrete Chiral Symmetry as the Origin of Families
نویسنده
چکیده
We construct a model for the quark mass and flavor mixing matrices, based on the hypothesis that the flavor weak eigenstates in the three families are distinguished by a spontaneously broken discrete Z6 chiral symmetry. In a leading partially symmetric approximation, the model accommodates the family mass spectra, with a CKM matrix that is exactly unity. Adding small asymmetries in first order perturbation theory gives a CKM matrix with the correct qualitative structure, with s23/s12 and s13/s12 naturally of order Ms/Mb.

Model for Particle Masses, Flavor Mixing, and CP Violation, Based on Spontaneously Broken Discrete Chiral Symmetry as the Origin of Families
We construct extensions of the standard model based on the hypothesis that the Higgs bosons also exhibit a family structure, and that the flavor weak eigenstates in the three families are distinguished by a discrete Z6 chiral symmetry that is spontaneously broken by the Higgs sector. We study in detail at the tree level models with three Higgs doublets, and with six Higgs doublets comprising tw...
متن کاملFlavor Symmetries and the Description of Flavor Mixing
It is shown that the hierarchical structure of the quark mass terms in the standard model suggests a new description of the flavor mixing. The latter is primarily a heavy quark mixing involving the t and b quarks, followed by a mixing exclusively in the uchannel or the d-channel. The complex phase describing CP violation arises only in the light quark sector. The Cabibbo angle is not a basic pa...
متن کاملModels of Flavor with Discrete Symmetries
In an attempt to understand the observed patterns of lepton and quark masses, models invoking a flavor symmetry Gf , under which the Standard Model generations are charged, have been proposed. One particularly successful symmetry, U(2), has been extensively discussed in the literature. The Yukawa matrices in models based on this symmetry reproduce the observed mass ratios in the lepton and quar...
متن کاملDiscrete Flavor Symmetries and Mass Matrix Textures
We show how introducing discrete Abelian flavor symmetries can produce texture zeros in the fermion mass matrices, while preserving the correct relationships with the low-energy data on quark and lepton masses. We outline a procedure for defining texture zeros as suppressed entries in Yukawa matrices. These texture zeros can account for the coexistence of the observed large mixing in atmospheri...
متن کاملMass Matrix Related to Up - Quark Masses and Nearly Tribimaximal Mixing – Based on a Yukawaon model –
Based on a new approach (the so-called Yukawaon model) to the mass spectra and mixings, a neutrino mass matrix which is described in terms of the up-quark masses and CKM matrix parameters is proposed. The mass matrix successfully leads to a nearly tribimaximal mixing without assuming any discrete symmetry. 1 What is a Yukawaon model? In the standard model of the quarks and leptons, we have many...
