Flavor 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 کاملBilarge Leptonic Mixing and Lepton Masses from Flavor Symmetries
We present a model for leptonic mixing and the lepton masses based on anomalous U(1) charges and a non-Abelian flavor symmetry. The model yields bilarge leptonic mixing, an inverted neutrino mass spectrum and hierarchical charged lepton masses. The non-Abelian flavor symmetry enforces an approximately maximal atmospheric mixing angle and predicts the relation θ12 π4 − θ13 between the solar and ...
متن کاملThe Kinematics and Dynamics of Flavor Mixing
In view of the observed strong hierarchy of the quark and lepton masses and of the flavor mixing angles, it is argued that the description of flavor mixing must take this into account. One particularly interesting way to describe the flavor mixing, which, however, is not the one used today, emerges, which is particularly suited for models of quark mass matrices based on flavor symmetries. We co...
متن کاملNon-Abelian Discrete Flavor Symmetries
This is an incomplete survey of some non-Abelian discrete symmetries which have been used recently in attempts to understand the flavor structure of leptons and quarks. To support such symmetries, new scalar particles are required. In some models, they are very massive, in which case there may not be much of a trace of their existence at the TeV scale. In other models, they are themselves at th...
متن کاملTheory of Neutrino Flavor Mixing
The depth of our theoretical understanding of neutrino flavor mixing should match the importance of this phenomenon as a herald of long-awaited empirical challenges to the standard model of particle physics. After reviewing the familiar, simplified quantum mechanical model and its flaws, I sketch the deeper understanding of both vacuum and matter-enhanced flavor mixing that is found in the fram...
