Neutrino Masses and Mixings with Flavor Symmetries

چکیده

Recent atmospheric neutrino data at Super-Kamiokande suggest the large flavor mixing of neutrinos. Models for the lepton mass matrix, which give the near-maximal flavor mixing, are discussed in the three family model. Especially, details of the models with the S 3 or O(3) flavor symmetry are studied.

Natural Neutrino Masses and Mixings from Warped Geometry

We demonstrate that flavor symmetries in warped geometry can provide a natural explanation for large mixing angles and economically explain the distinction between the quark and lepton flavor sectors. We show how to naturally generate Majorana neutrino masses assuming a gauged a U(1)B−L symmetry broken in the UV that generates seesaw masses of the right size. This model requires lepton minimal ...

Approximate flavor symmetries in the lepton sector.

Approximate flavor symmetries in the quark sector have been used as a handle on physics beyond the Standard Model. Due to the great interest in neutrino masses and mixings and the wealth of existing and proposed neutrino experiments it is important to extend this analysis to the leptonic sector. We show that in the see-saw mechanism, the neutrino masses and mixing angles do not depend on the de...

Generation of Neutrino Masses and Mixings in Gauge Theories

Recent experimental data of neutrinos make big impact on the neutrino masses and their mixings. Most exciting one is the results at Super-Kamiokande on the atmospheric neutrinos, which indicate the large neutrino flavor oscillation of νμ → νx . Solar neutrino data also provide the evidence of the neutrino oscillation, however this problem still uncertain . What can we learn from these results? ...

0 Large Lepton Flavor Mixings in SU ( 6 ) × SU ( 2 ) R Model

The lepton masses and mixings are studied on the basis of string inspired SU(6) × SU(2)R model with global flavor symmetries. Provided that sizable mixings between lepton doublets L and Higgsino-like fields Hd with even R-parity occur and that seesaw mechanism is at work in the neutrino sector, the model can yield a large mixing angle solution with tan θ12, tan θ23 = O( √ λ) (λ = 0.22), which i...
