Single-wave solutions of the neutrino fast flavor system. Part II. Weak instabilities and their resonant behavior

Journal of High Energy Physics
Flavor instabilities in dense neutrino media trigger exponential growth of flavor waves, yet their nonlinear saturation remains poorly understood. We examine a simple proxy for this effect in the form of a single-wave solution of an axially symmetric ...

Theory of neutrino masses and mixing [PDF]

Nuclear Physics B - Proceedings Supplements, 2003
In this talk I will review our present knowledge on neutrino masses and mixing trying to emphasize what has been definitively proved and what is in the process of being probed. I will also discuss the most important theoretical implications of these results: the existence of new physics, the estimate of the scale of this new physics as well as some ...

Current and future neutrino oscillation constraints on leptonic unitarity

Journal of High Energy Physics, 2020
The unitarity of the lepton mixing matrix is a critical assumption underlying the standard neutrino-mixing paradigm. However, many models seeking to explain the as-yet-unknown origin of neutrino masses predict deviations from unitarity in the mixing of ...

Dispersion relation of the neutrino plasma: unifying fast, slow, and collisional instabilities

Journal of High Energy Physics
In neutrino-dense astrophysical environments, these particles exchange flavor through a coherent weak field, forming a collisionless neutrino plasma with collective flavor dynamics.

FLAVOR SYMMETRIES, NEUTRINO MASSES AND NEUTRINO MIXING

International Journal of Modern Physics A, 2008
We discuss the neutrino mixing, using the texture 0 mass matrices, which work very well for the quarks. The solar mixing angle is directly linked to the mass ratio of the first two neutrinos. The neutrino masses are hierarchical, but the mass ratios turn out to be much smaller than for quarks. The atmospheric mixing angle is 38°.

Status of neutrino mass and mixing [PDF]

International Journal of Modern Physics A, 2014
In the last two decades experiments have established the existence of neutrino oscillations and most of the related parameters have by now been measured with reasonable accuracy. These results have accomplished a major progress for particle physics and cosmology.

Flavour-symmetric type-II Dirac neutrino seesaw mechanism

Physics Letters B, 2018
We propose a Standard Model extension with underlying A4 flavour symmetry where small Dirac neutrino masses arise from a Type-II seesaw mechanism. The model predicts the “golden” flavour-dependent bottom-tau mass relation, requires an inverted neutrino ...
