Neutrino mass, mixing and discrete symmetries

Status of the discrete symmetry approach to explanation of the lepton masses and mixing is summarized in view of recent experimental results, in particular, establishing relatively large 1-3 mixing. The lepton mixing can originate from breaking of discrete flavor symmetry Gf to different residual symmetries Gl and Gν in the charged lepton and neutrino sectors. In this framework the symmetry gro...

One-loop renormalization group equations of the neutrino mass matrix in the triplet seesaw model

Within the framework of the standard model plus one heavy Higgs triplet, we derive a full set of one-loop renormalization group equations of the neutrino mass matrix and Higgs couplings in both full and effective theories. The explicit RGEs of neutrino masses, flavor mixing angles and CP-violating phases are also obtained, and their non-trivial running behaviors around the Higgs triplet mass th...

Pulsar Velocities without Neutrino Mass

One of the most challenging problems in modern astrophysics is to find a consistent explanation for the high velocity of pulsars. Observations [1] show that these velocities range from zero up to 900 km/s with a mean value of 450 ± 50 km/s . An attractive possibility is that pulsar motion arises from an asymmetric neutrino emission during the supernova (SN) explosion. In fact, neutrinos carry m...

Neutrino Mass Matrices in Models with Horizontal Symmetries

We have studied the most general neutrino mass matrices in models with SU(2) and SU(3) horizontal symmetries. Without going into the details of the models it is possible to write down the effective operators, which predict the structure of the Majorana neutrino mass matrices. Unlike other extensions of the standard model, the structure is now independent of the effective Yukawa couplings and de...

Minimalistic Neutrino Mass Model

We consider the simplest model which solves the solar and atmospheric neutrino puzzles, in the sense that it contains the smallest amount of beyond the Standard Model ingredients. The solar neutrino data is accounted for by Planck-mass effects while the atmospheric neutrino anomaly is due to the existence of a single righthanded neutrino at an intermediate mass scale between 109 GeV and 1014 Ge...
