Fast neutrino flavor instability and neutrino flavor lepton number crossings
نویسندگان
چکیده
In this paper, we show the equivalency between existence of fast neutrino flavor instability and that lepton number (NFLN) crossings, which indicates an NFLN angular distribution takes both signs. The veracity proposition has been uncertain sometimes controversial despite its indispensability in evolutions dense neutrinos. This study clarifies occurrence crossing is necessary sufficient for instability.

Neutrino oscillation experiments and limits on lepton–number and lepton–flavor violating processes
Using a three neutrino framework we investigate bounds for the effective Majorana neutrino mass matrix. The mass measured in neutrinoless double beta decay is its 11 element. Lepton–number and –flavor violating processes sensitive to each element are considered and limits on branching ratios or cross sections are given. Those processes include μ−e+ conversion, K+ → π−μ+μ+ or recently proposed h...
متن کاملBi-maximal Lepton Flavor Mixing Matrix and Neutrino Oscillation
Recently, many authors showed that if the solar and atmospheric neutrino data are both described by maximal mixing vacuum oscillations at the relevant mass scale, then there exists a unique bi-maximal lepton mixing matrix for three neutrino flavors. We construct the lepton mass matrices from the symmetry principle so that maximal mixings for the atmospheric and the solar neutrino vacuum oscilla...
متن کاملSO ( 3 ) Gauge Symmetry and Neutrino - Lepton Flavor Physics
Based on the SO(3) gauge symmetry for three family leptons and general see-saw mechanism, we present a simple scheme that allows three nearly degenerate Majorana neutrino masses needed for hot dark matter. The vacuum structure of the spontaneous SO(3) symmetry breaking can automatically lead to a maximal CP-violating phase. Thus the current neutrino data on both the atmospheric neutrino anomaly...
متن کاملLepton flavor violation and the tau neutrino mass.
We point out that, in the left-right symmetric model of weak interactions, if ντ mass is in the keV to MeV range, there is a strong correlation between rare decays such as τ → 3μ, τ → 3e and the ντ mass. In particular, we point out that a large range of ντ masses are forbidden by the cosmological constraints on mντ in combination with the present upper limits on these processes. † Work supporte...
متن کاملFlavor Mixing, Neutrino Masses and Neutrino Oscillations
We study a model for the mass matrices of the leptons. We are able to relate the mass eigenvalues of the charged leptons and of the neutrinos to the mixing angles and can predict the masses of the neutrinos. We find a normal hierarchy the masses are 0.004 eV, 0.01 eV and 0.05 eV. The atmospheric mixing angle is given by the mass ratios of the charged leptons and the neutrinos. We find 38 degree...
