An Explicit Model of Quark Mass Matrix
A physical model which describes the CKM matrix is analyzed. The elements of such a matrix are field-strength renormalization factors. Each column gives the probability amplitude for the field operators of the coupled Lagrangian to create a one-particle eigenfunction of definite energy. The total conserved charge is the sum of the flavor charges which are not conserved separately. This work is ...
متن کاملPhenomenological quark-lepton mass relations and neutrino mass estimations
Based on the experimental data and estimations of the charged leptons and quark masses, a close power law with exponent 3/4 has been found, connecting the charged lepton masses and up quarks masses. It has been shown that this approximation is considerably better than any known approach. A similar mass relation has been suggested for the masses of the neutral leptons and down quarks. The latter...
متن کاملPhenomenological Meaning of a Neutrino Mass Matrix Related to Up-Quark Masses
Recently, a curious neutrino mass matrix has been proposed: it is related to up-quark masses, and it can excellently give a nearly tribimaxial mixing. It is pointed out that, in order to obtain such successful results, three phenomenological relations among masses and CKM parameters must be simultaneously satisfied. This suggests that there must be a specific flavor-basis in which down-quark an...
متن کاملPhenomenological Analysis of Lepton and Quark Mass Matrices
We propose a model that all quark and lepton mass matrices originally have the same zero texture. Namely their (1,1), (1,3) and (3,1) components are zeros. For the neutrino mass matrix, we further impose the symmetry between the second and the third generations. Then the neutrino mass matrix has a maximal νμ ντ mixing. Our model is consistent with all the neutrino oscillation experiments and th...
متن کاملNew Estimate of Quark Mass Parameters*
An estimate of quark mass parameters suitable for the study of chiral symmetry breaking effects is made using exact GoldbergerTreiman relations for the Goldstone bosons which appear in the WeinbergSalam theory when the gauge coupling is set to zero. The numbers obtained are m U = 13.75 5.9 MeV, md = 24.7t12.9 MeV, and ms = 4972 299 MeV. Consistency of the various Goldberger-Treiman relations wi...
