Mass relations among family members of quarks and leptons

چکیده
The various mass relations among members of quark and lepton families are given. Three mass relations for the charm, beauty, and top quark family members are given and three mass relations for the electron, muon, and tau lepton family members are presented. Quantum Choromodynamics (QCD), the theory of strong interactions, is unique among physical theories in its combination of logical closure and empirical success. In the asymptotic Bjorken limit, the study of the properties of strong interactions has proved to be one of the most creative ideas [1]. In Regge asymptotics, the number of partons increases rapidly due to QCD bremsstrahlung, relatively little work has been done. This limit of strong interactions, which we shall call the Regge limit, was studied intensively in the 60’s and indeed led eventually to string theory [2]. The rapid growth in the number of partons due to QCD bremsstrahlung in the leading logrithmic approximation is described by the BFKL equation [3]. There is a sense in which QCD is better than it has to be. It is not a complete theory of the world. Even within the standard model quarks have additional interactions, beyound QCD, that become significant – indeed, problematic – at short distances [4]. In the words of Professor Frank Wilczek, “I find QCD disturbing that it takes vast computer resources, careful limiting procedures, to simulate the mass and properties of a proton with decent accuracy. And for real time

متن کاملFlavor Mixing, Quark Masses, Neutrino Masses and Neutrino Oscillations
We discuss first the flavor mixing of the quarks, using the texture zero mass matrices. Then we study a similar model for the mass matrices of the leptons. We are able to relate the mass eigenvalues of the charged leptons and of the neutrinos to the mixing angles and can predict the masses of the neutrinos. We find a normal hierarchy the masses are 0.004 eV, 0.01 eV and 0.05 eV. The atmospheric...
متن کاملMixing of Charge −1/3 Quarks and Charged Leptons with Exotic Fermions in E6
A way is suggested to understand why the average masses of (d, s, b) quarks are smaller than those of (u, c, t) quarks. In contrast to previously proposed mechanisms relying on different Higgs boson vacuum expectation values or different Yukawa couplings, the mass difference is explained as a consequence of mixing of (d, s, b) with exotic quarks implied by the electroweak-strong unification gro...

متن کاملLeptonic Fritzsch Matrices and Neutrino Oscillations
It was recently shown by the authors that the Fritzsch ansatz for the quark mass matrices prescribed at the supersymmetric grand unified scale is compatible with a moderately heavy top quark (mt ≃ 120−150 GeV ). Here we extend the ansatz to incorporate the charged leptons and the neutrinos. It is found that the νe− νμ mixing angle is small and consistent with the MSW solution of the solar neutr...
