Neutrino mixing

open access: yesJournal 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

open access: yesNuclear 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]

open access: yesEPJ 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 ...

A neutrino mass-mixing sum rule from SO(10) and neutrinoless double beta decay

open access: yesJournal of High Energy Physics, 2017
Minimal SO(10) grand unified models provide phenomenological predictions for neutrino mass patterns and mixing. These are the outcome of the interplay of several features, namely: i) the seesaw mechanism; ii) the presence of an intermediate scale where B-

NuFit-6.0: updated global analysis of three-flavor neutrino oscillations [PDF]

open access: yesJournal of High Energy Physics
We present an updated global analysis of neutrino oscillation data as of September 2024. The parameters θ12, θ13, $$ \Delta {m}_{21}^2 $$ ∆ m 21 2 , and $$ \mid \Delta {m}_{3\ell}^2\mid $$ ∣ ∆ m 3 ℓ 2 ∣ (ℓ = 1, 2) are well ...

Neutrino mass and mixing with A5 modular symmetry [PDF]

open access: yesPhysical Review D, 2019
We present a comprehensive analysis of neutrino mass and lepton mixing in theories with $A_5$ modular symmetry. We construct the weight 2, weight 4 and weight 6 modular forms of level 5 in terms of Dedekind eta-functions and Klein forms, and their ...

Unifying leptogenesis, dark matter and high-energy neutrinos with right-handed neutrino mixing via Higgs portal [PDF]

open access: yes, 2016
We revisit a model in which neutrino masses and mixing are described by a two right-handed (RH) neutrino seesaw scenario, implying a strictly hierarchical light neutrino spectrum.

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

open access: yesNew 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

Sensitivity to sterile neutrino mixing using reactor antineutrinos

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The reactor antineutrinos are used for the precise measurement of oscillation parameters in the 3-neutrino model, and also used to investigate active-sterile neutrino mixing sensitivity in the $$3+1$$ 3+1 neutrino framework. In the present work, we study

Models of neutrino masses and mixings [PDF]

open access: yesNew 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.
