Flavor Symmetry for Quarks and Leptons
Present data on neutrino masses and mixing favor the highly symmetric tribimaximal neutrino mixing matrix which suggests an underlying flavor symmetry. A systematic study of non-abelian finite groups of order g ≤ 31 reveals that tribimaximal mixing can be derived not only from the well known tetrahedral flavor symmetry T ≡ A4, but also by using the binary tetrahedral symmetry SL2(F3) which does...
متن کاملFlavor Mixing with Quarks and Leptons*
The last year has brought such a wealth of new information on heavy flavors _ that meaningful bounds can now be placed on all fermion mass related parameters -. in the Standard Model. I review the status of the KM matrix with particular emphasis on the theoretical uncertainties. B” -B’ mixing is reevaluated and CP violation is discussed as it is observed in KL decays and as it hopefully can be ...
متن کاملFlavor Physics with light quarks and leptons
The impact of rare K decays and lepton-flavor violating processes in shedding light on physics beyond the Standard Model is reviewd. To this purpose, I first recall the formulation of the Minimal Flavor Violation hypothesis –both in the quark and in the lepton sector– and then use it as guiding principle in comparing the new-physics sensitivity of different rare processes. On the phenomenologic...
متن کاملFlavor and CP Violations from Sleptons at the Muon Collider
Supersymmetric theories generally have new flavor and CP violation sources in the squark and slepton mass matrices. They will contribute to the lepton flavor violation processes, such as μ → eγ, which can be probed far below the current bound with an intense muon source at the front end of the muon collider. In addition, if sleptons can be produced at the muon collider, the flavor violation can...
متن کاملMass and Flavor Mixing Schemes of Quarks and Leptons
We give an overview of recent progress in the study of fermion mass and flavor mixing phenomena. The hints exhibited by the quark and lepton mass spectra towards possible underlying flavor symmetries, from which realistic models of mass generation could be built, are emphasized. A variety of schemes of quark mass matrices at low and superhigh energy scales are described, and their consequences ...
