Friedberg-Lee Symmetry for Quark Masses and Flavor Mixing
We point out a generic correlation between the Friedberg-Lee symmetry of quark mass operators and the vanishing of quark masses. We make phenomenological explorations on two textures of quark mass matrices with the broken Friedberg-Lee symmetry. We present a new pattern of quark mass matrices in agreement with current experimental data. Both analytical and numerical results of our calculations ...
متن کاملNeutrino Sector with Majorana Mass Terms and Friedberg-Lee Symmetry
We examine a recently proposed symmetry/condition by Friedberg and Lee in the framework where three right-handed neutrinos are added to the spectrum of the three-family Minimal Standard Model. It is found that the right-handed neutrinos are very special, with respect to this symmetry. In the symmetry limit the neutrinos are massless and that may be a hint about why they are light. Imposed as a ...
متن کاملNeutrino Mixing : from the Broken μ - τ Symmetry to the Broken Friedberg - Lee Symmetry
I argue that the observed flavor structures of leptons and quarks might imply the existence of certain flavor symmetries. The latter should be a good starting point to build realistic models towards deeper understanding of the fermion mass spectra and flavor mixing patterns. The µ-τ permutation symmetry serves for such an example to interpret the almost maximal atmospheric neutrino mixing angle...
متن کاملA generalization of Lee codes
Motivated by a problem in computer architecture we introduce a notion of the perfect distance-dominating set, PDDS, in a graph. PDDS s constitute a generalization of perfect Lee codes, diameter perfect codes, as well as other codes and dominating sets. In this paper we initiate a systematic study of PDDS s. PDDS s related to the application will be constructed and the non-existence of some PDDS...
متن کامل0 M ar 1 99 7 Dynamical properties of flux tubes in the Friedberg - Lee model
A dynamical model of confinement based on a microscopic transport description of the Friedberg-Lee model is extended to explicit color degrees of freedom. The string tension is reproduced by an adiabatic string formation from the nu-cleon ground state. As a particular application, we address the question of how a charmonium state might be dissociated by the strong color electric fields when mov...
