Trimaximal neutrino mixing from modular A4 invariance with residual symmetries [PDF]
Physics Letters B, 2019 We construct phenomenologically viable models of lepton masses and mixing based on modular A4 invariance broken to residual symmetries Z3T or Z3ST and Z2S respectively in the charged lepton and neutrino sectors. In these models the neutrino mixing matrix

Discrete flavour symmetries, neutrino mixing and leptonic CP violation [PDF]
European Physical Journal C: Particles and Fields, 2018 The current status of our knowledge of the 3-neutrino mixing parameters and of the CP violation in the lepton sector is summarised. The non-Abelian discrete symmetry approach to understanding the observed pattern of neutrino mixing and the related ...

Trimaximal neutrino mixing from scotogenic A4 family symmetry [PDF]
Physics Letters B, 2021 We propose a flavor theory of leptons implementing an A4 family symmetry. Our scheme provides a simple way to derive trimaximal neutrino mixing from first principles, leading to simple and testable predictions for neutrino mixing and CP violation.

Testing sterile neutrino mixing with present and future solar neutrino data [PDF]
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

Neutrino mixing and leptonic CP violation from S 4 flavour and generalised CP symmetries [PDF]
Journal of High Energy Physics, 2017 We consider a class of models of neutrino mixing with S 4 lepton flavour symmetry combined with a generalised CP symmetry, which are broken to residual Z 2 and Z 2 × H CP ν symmetries in the charged lepton and neutrino sectors, respectively, H CP ν being

Bounds on lepton non-unitarity and heavy neutrino mixing [PDF]
Journal of High Energy Physics, 2023 We present an updated and improved global fit analysis of current flavour and electroweak precision observables to derive bounds on unitarity deviations of the leptonic mixing matrix and on the mixing of heavy neutrinos with the active flavours. This new

Nonunitary neutrino mixing in short and long-baseline experiments [PDF]
Physical Review D, 2021 Non-unitary neutrino mixing in the light neutrino sector is a direct consequence of type-I seesaw neutrino mass models. In these models, light neutrino mixing is described by a sub-matrix of the full lepton mixing matrix and, then, it is not unitary in ...

Improved Constraints on Sterile Neutrino Mixing from Disappearance Searches in the MINOS, MINOS+ , Daya Bay, and Bugey-3 Experiments [PDF]
Physical Review Letters, 2020 Searches for electron antineutrino, muon neutrino, and muon antineutrino disappearance driven by sterile neutrino mixing have been carried out by the Daya Bay and MINOS+ collaborations.

Neutrino-4 anomaly: Oscillations or fluctuations?
Physics Letters B, 2021 We present a deep study of the Neutrino-4 data aimed at finding the statistical significance of the large-mixing short-baseline neutrino oscillation signal claimed by the Neutrino-4 collaboration at more than 3σ. We found that the results of the Neutrino-
