Neutrino Masses and Mixings∗
The neutrino was proposed in 1930 by Pauli and solved the problem of the ”missing energy” in beta decay, n → p + e− + ν̄. It had to be a fermion with the same spin as the electron, but its mass should be extremely small, because the threshold being in essence the sum of proton and electron masses. The neutrino was only experimentally established in 1956 by Reines and Cowan via the inverse beta d...
متن کاملNeutrino masses and mixings
We propose a novel theoretical understanding of neutrino masses and mixings, which is attributed to the intrinsic vector-like feature of the regularized Standard Model at short distances. We try to explain the smallness of Dirac neutrino masses and the decoupling of the right-handed neutrino as a free particle. Neutrino masses and mixing angles are completely related to each other in the Schwin...
متن کاملNeutrino Masses and Mixings
Theoretical prejudices, cosmology, and neutrino oscillation experiments all suggest neutrino masses are far below present direct experimental limits. Four interesting scenarios and their implications are discussed: (I) a 17 keV v,, (2) a 30 eVv, making up the dark matter, (3) a 10e3 eVu,, 10 solve the solar neutrino problem, and (4) a three-neutrino M S W solution. @ L.

A brief overview of some of the ideas to understand small neutrino masses and large neutrino mixings are presented.
متن کاملMinimal Model for Neutrino Masses and Mixings
Working in the framework of three chiral neutrinos with Majorana masses, we investigate a scenario first realized in an explicit model by Zee: that the neutrino mass matrix is strictly off-diagonal in the flavor basis, with all its diagonal entries precisely zero. This CP-conserving ansatz leads to two relations among the three mixing angles (θ1, θ2, θ3) and two squared mass differences. We imp...
