Neutrino mixing from finite modular groups [PDF]
Physical Review D, 2018 We study the lepton flavor models, whose flavor symmetries are finite subgroups of the modular group such as $S_3$ and $A_4$. In our models, couplings are also nontrivial representations of these groups and modular functions of the modulus.

Radiative magnification of neutrino mixings and a natural explanation of the neutrino anomalies [PDF]
, 2000 We show that the neutrino mixing pattern with the large mixing required for the atmospheric neutrino problem and the small mixing angle MSW solution for the solar neutrino problem can be naturally generated through radiative magnification, even though ...

Displaced vertex signatures of a pseudo-Goldstone sterile neutrino
Journal of High Energy Physics, 2021 Low-scale models of neutrino mass generation often feature sterile neutrinos with masses in the GeV-TeV range, which can be produced at colliders through their mixing with the Standard Model neutrinos.

Modular A4 invariance and neutrino mixing [PDF]
Journal of High Energy Physics, 2018 We study the phenomenological implications of the modular symmetry Γ(3) ≃ A4 of lepton flavors facing recent experimental data of neutrino oscillations.

Scotogenic S3 symmetric generation of realistic neutrino mixing [PDF]
Physical Review D, 2019 Realistic neutrino mixing is achieved at one-loop level radiatively using $S3\times Z_2$ symmetry. The model comprises of two right-handed neutrinos, maximally mixed to produce the structure of the left-handed Majorana neutrino mass matrix characterized ...

Displaced vertices as probes of sterile neutrino mixing at the LHC [PDF]
Physical Review D, 2018 We investigate the reach at the LHC to probe light sterile neutrinos with displaced vertices. We focus on sterile neutrinos $N$ with masses $m_{N} \sim $ (5-30) GeV, that are produced in rare decays of the Standard Model gauge bosons and decay inside the

Improved sensitivities of ESSνSB from a two-detector fit
Journal of High Energy Physics, 2023 We discuss the improvement of the sensitivity of ESSνSB to the discovery of CP violation and to new neutrino physics which can be obtained with a two-detector fit of the data of the near and far detectors. In particular, we consider neutrino non-standard

Assessing the viability of A4 , S4 , and A5 flavor symmetries for description of neutrino mixing [PDF]
Physical Review D, 2018 We consider the A4, S4, and A5 discrete lepton flavor symmetries in the case of 3-neutrino mixing, broken down to nontrivial residual symmetries in the charged lepton and neutrino sectors in such a way that at least one of them is a Z2.

Bounds on light sterile neutrino mass and mixing from cosmology and laboratory searches [PDF]
Physical Review D, 2020 We provide a consistent framework to set limits on properties of light sterile neutrinos coupled to all three active neutrinos using a combination of the latest cosmological data and terrestrial measurements from oscillations, $\beta$-decay and ...

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
