Relation between quark masses and weak mixings
نویسندگان
چکیده
Simple transformation formulas between fermion matrices and observables, and numerical values of quark matrices, are obtained on a particular weak basis with one quark matrix diagonal and the other with vanishing elements 1-1, 1-3 and 3-1, and with only the element 2-2 complex. When we chooseMu diagonal, thenMd shows intriguing numerical properties which suggest a four parameter description of it, which implies Vus ≃ √ md/ms, Vcb ≃ (3/ √ 5)(ms/mb) and Vub ≃ (1/ √ 5)( √ mdms/mb). Few comments on mass-mixing relations are added. PACS numbers: 12.15.Ff, 12.15.Hh

Quark masses and weak couplings in the SM and beyond
I discuss two topics: i) the empirical adequacy of the Standard Model in the Flavour Sector in view of recent data; ii) the possible existence of a hidden structure in the quark masses and mixings based on textures.
متن کاملInvariant formulation of CP violation for four quark families
We find a minimal set of constraints which are independent of the choice of weak quark basis and necessary and sufficient for CP conservation for four quark families, including also the case of degenerate quark masses. These invariant conditions are written in the mass eigenstate basis as a function of the fermion masses and charged current mixings. CP violation is then related to the areas of ...
متن کاملClassification and Application of Triangular Quark Mass Matrices
The hierarchical structure in the quark masses and mixings allows its ten physical parameters to be most conveniently encoded in mass matrices of the upper triangular form. We classify these matrices in the hierarchical, minimal parameter basis where the mismatch between the weak and mass eigenstates involves only small mixing angles. Ten such pairs are obtained for the up and down quarks. This...
متن کاملLepton mass matrices from a quark-lepton analogy
We study the implications of having a similarity between quark and lepton mixing in the Dirac sector of the Standard Model plus the right-handed neutrino. This enable us to describe all masses and mixings in the Dirac sector in terms of only five parameters: three mass scales mb, mτ and mt, one parameter λ describing all the mixings, and a CP violating phase in the quark sector. Then, from expe...
متن کاملFermion masses and mixings in gauge theories
The recent evidence for neutrino oscillations stimulate us to discuss again the problem of fermion masses and mixings in gauge theories. In the standard model, several forms for quark mass matrices are equivalent. They become ansatze within most extensions of the standard model, where also relations between quark and lepton sectors may hold. In a seesaw framework, these relations can constrain ...
