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

Damping of neutrino oscillations, decoherence and the lengths of neutrino wave packets
Journal of High Energy Physics, 2022 Spatial separation of the wave packets (WPs) of neutrino mass eigenstates leads to decoherence and damping of neutrino oscillations. Damping can also be caused by finite energy resolution of neutrino detectors or, in the case of experiments with ...

Neutrino mass and mixing with A5 modular symmetry [PDF]
Physical 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 ...

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 ...

Mixed states for mixing neutrinos [PDF]
Physical Review D, 2018 Ici, nous discutons de la description des neutrinos de saveur produits ou détectés dans des processus qui impliquent plus d'un neutrino. Nous montrons que dans ces cas, les neutrinos de saveur ne peuvent pas être décrits séparément par des états purs, mais nécessitent une description de la matrice de densité. Nous considérons explicitement les exemples

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 ...

Democratic neutrino mixing reexamined
Physics Letters B, 2004 We reexamine the democratic neutrino mixing ansatz, in which the mass matrices of charged leptons and Majorana neutrinos arise respectively from the explicit breaking of S(3)_L x S(3)_R and S(3) flavor symmetries. It is shown that a democracy term in the neutrino sector can naturally allow the ansatz to fit the solar neutrino mixing angle _sun ...

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 ...

Bi-Maximal Neutrino Mixing in the MSSM with a Single Right-Handed Neutrino [PDF]
, 1998 We discuss neutrino masses in the framework of a minimal extension of the minimal supersymmetric standard model (MSSM) consisting of an additional single right-handed neutrino superfield $N$ with a heavy Majorana mass $M$, which induces a single light ...
