Schemes of Neutrino Mixings (Oscillations) and Their Mixing Matrices

, 2004
Three schemes of neutrino mixings (oscillations) together with their mixing matrices (analogous to Kabibbo-Kobayashi-Maskawa matrices) are considered. In these schemes neutrino transitions are virtual if neutrino masses are different.

Constraints from Neutrino Oscillation Experiments on the Effective Majorana Mass in Neutrinoless Double $\beta$-Decay

, 1999
We determine the possible values of the effective Majorana neutrino mass $|< m > |= |\sum_j U_{ej}^2 m_j|$ in the different phenomenologically viable three and four-neutrino scenarios.

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.

Neutrino masses and flavor mixing [PDF]

Modern Physics Letters A, 2010
We discuss the neutrino oscillations, using texture zero mass matrices for the leptons. The reactor mixing angle θl is calculated. The ratio of the masses of two neutrinos is determined by the solar mixing angle. We can calculate the masses of the three neutrinos: m1 ≈ 0.003 eV , m2 ≈ 0.012 eV , m3 ≈ 0.048 eV .

Neutrino oscillation prospects with a dual-baseline beam from BNL to SNOLAB and SURF

Journal of High Energy Physics
The Electron-Ion Collider (EIC) is a next-generation accelerator primarily designed to study the internal structure of nucleons through high-precision electron-hadron collisions.

Parametrizing the neutrino mixing matrix [PDF]

Physical Review D, 2003
We propose parametrizations of the neutrino mixing matrix. We discuss several Ansatzes: in some of them $V_{e3}=0$ but in others $V_{e3}$ typically ``comes out'' to be of order $\simeq 0.05.$

Theory of neutrino slow flavor evolution. Part I. Homogeneous medium

Journal of High Energy Physics
Dense neutrino gases can exhibit collective flavor instabilities, triggering large flavor conversions that are driven primarily by neutrino-neutrino refraction.

Neutrino oscillations and scattering theory

Journal of High Energy Physics
We derive the neutrino oscillation probability in vacuum using scattering theory methods developed earlier in the context of collider physics [1–3]. It is computed from Feynman diagrams that combine neutrino production and detection processes into a ...

Confronting solutions of the Gallium Anomaly with reactor rate data

Physics Letters B
Recently, several models have been suggested to reduce the tension between Gallium and reactor antineutrino spectral ratio data which is found in the framework of 3+1 active-sterile neutrino mixing.
