Cobimaximal neutrino mixing from A4 and its possible deviation [PDF]
, 2017 It has recently been shown that the phenomenologically successful pattern of cobimaximal neutrino mixing ( , , and ) may be achieved in the context of the non-Abelian discrete symmetry A4, if the neutrino mass matrix is diagonaized by an orthogonal ...

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 ...

Insights into grand unified theories from current experimental data [PDF]
, 2015 In this thesis, we investigate several ways how the structure of a high energy particle physics model constituting a grand unification theory (GUT) in supersymmetry (SUSY) can be inferred from multiple types of information obtained at low energy ...

Predictions for the Majorana CP Violation Phases in the Neutrino Mixing Matrix and Neutrinoless Double Beta Decay [PDF]
, 2016 We obtain predictions for the Majorana phases α21/2α21/2 and α31/2α31/2 of the 3×33×3 unitary neutrino mixing matrix U=Ue†Uν, UeUe and UνUν being the 3×33×3 unitary matrices resulting from the diagonalisation of the charged lepton and neutrino Majorana ...

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 ...

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

Soft A4 → Z3 symmetry breaking and cobimaximal neutrino mixing [PDF]
, 2016 I propose a model of radiative charged-lepton and neutrino masses with A 4 symmetry. The soft breaking of A 4 to Z 3 lepton triality is accomplished by dimension-three terms. The breaking of Z 3 by dimension-two terms allows cobimaximal neutrino mixing (

Neutrino radiation hydrodynamics in hot and dense nuclear matter and the role of microphysics in simulations of massive stars [PDF]
, 2010 The main results of my doctoral studies were obtained from core collapse simulations of massive stars using a numerical model based on radiation hydrodynamics and three-flavour Boltzmann neutrino transport in spherical symmetry.

Sensitivity to sterile neutrino mixing using reactor antineutrinos
European 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

Status and prospects of global analyses of neutrino mass-mixing parameters [PDF]
, 2017 We discuss the present knowledge of the neutrino oscillation parameters, the two mass squared differences (Î ́m2, Îm2), the three mixing angles (Î ̧12, Î ̧13, Î ̧23) and one phase Î ́.
