Neutrino mixing

Journal of Physics G: Nuclear and Particle Physics, 1991
In the first part of these lectures the neutrino mixing hypothesis will be considered in detail. We will discuss the possible schemes of neutrino mixing and present the data of the recent experiments searching for effects due to nonvanishing neutrino masses and mixing angles.In the second part of these lectures the physics of solar neutrinos will be ...

Non-zero θ13 and δCP phase with A4 flavor symmetry and deviations to tri-bi-maximal mixing via Z2 × Z2 invariant perturbations in the neutrino sector

Nuclear Physics B, 2022
In this work, a flavour theory of a neutrino mass model based on A4 symmetry is considered to explain the phenomenology of neutrino mixing. The spontaneous symmetry breaking of A4 symmetry in this model leads to tribimaximal mixing in the neutrino sector

A Phenomenological Model of Effectively Oscillating Massless Neutrinos and Its Implications [PDF]

EPJ Web of Conferences, 2020
We discuss an alternative picture of neutrino oscillation. In this phenomenological model, the flavor-changing phenomena of massless neutrinos arise from scattering processes between neutrinos and four types of undetected spin-0 massive particles ...

Theoretical Prospects of Neutrinoless Double Beta Decay

, 2005
The compelling experimental evidences for oscillations of solar and atmospheric neutrinos imply the existence of 3-neutrino mixing in vacuum. We briefly review the phenomenology of 3-neutrino mixing, and the current data on the 3-neutrino mixing ...

Testing sterile neutrino mixing with present and future solar neutrino data

European Physical Journal C: Particles and Fields, 2022
We investigate the sensitivity of solar neutrino data to mixing of sterile neutrinos with masses $$\gtrsim $$ ≳  eV. For current data, we perform a Feldman–Cousins analysis to derive a robust limit on the sterile neutrino mixing. The solar neutrino limit

CP Violation in Bilarge Lepton Mixing [PDF]

, 2002
We propose a scheme of lepton mixing in which the unitary matrix that diagonalizes the neutrino mass matrix is bimaximal and the deviation from bimaximal of the lepton mixing matrix is due to the unitary matrix that diagonalizes the charged-lepton mass ...

Prediction of leptonic CP phase from perturbatively modified tribimaximal (or bimaximal) mixing

, 2014
We consider the perturbatively modified tribimaximal (or bimaximal) mixing to estimate the (Dirac-type) CP phase in neutrino mixing matrix. The expressions for the CP phase are derived from the equivalence between the standard parametrization of the ...

Constraints on Exotic Mixing of Three Neutrinos [PDF]

, 1999
Exotic explanations are considered for atmospheric neutrino observations. Our analysis includes matter effects and the mixing of all three neutrinos under the simplifying assumption of only one relevant mixing scale. Constraints from accelerator, reactor

Models of neutrino masses and mixings [PDF]

New Journal of Physics, 2004
We review theoretical ideas, problems and implications of neutrino masses and mixing angles. We give a general discussion of schemes with three light neutrinos. Several specific examples are analyzed in some detail, particularly those that can be embedded into grand unified theories.

Predicting leptonic CP phase by considering deviations in charged lepton and neutrino sectors

New Journal of Physics, 2015
Recently, the reactor mixing angle ${\theta }_{13}$ has been measured precisely by Daya Bay, RENO, and T2K experiments with a moderately large value. However, the standard form of neutrino mixing patterns such as bimaximal, tri-bimaximal, golden ratio of
