On neutrino mixing in matter and CP and T violation effects in neutrino oscillations

Physics Letters B, 2018
Aspects of 3-neutrino mixing and oscillations in vacuum and in matter with constant density are investigated working with a real form of the neutrino Hamiltonian.

Theory of neutrino fast flavor evolution. Part II. Solutions at the edge of instability

Journal of High Energy Physics
In dense neutrino environments, such as provided by core-collapse supernovae or neutron-star mergers, neutrino angular distributions may be unstable to collective flavor conversions, whose outcome remains to be fully understood.

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.

Flavor Democracy and Type-II Seesaw Realization of Bilarge Neutrino Mixing

, 2004
We generalize the democratic neutrino mixing Ansatz by incorporating the type-II seesaw mechanism with S(3) flavor symmetry. We find that bilarge neutrino mixing can naturally appear if the flavor democracy contribution is strongly suppressed due to ...

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.

Modular S 4 models of lepton masses and mixing

Journal of High Energy Physics, 2019
We investigate models of charged lepton and neutrino masses and lepton mixing based on broken modular symmetry. The matter fields in these models are assumed to transform in irreducible representations of the finite modular group Γ4 ≃ S 4. We analyse the

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 ...
