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

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

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 ...

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

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.

Search for the sterile neutrino mixing with the ICAL detector at INO [PDF]
European Physical Journal C: Particles and Fields, 2017 The study has been carried out on the prospects of probing the sterile neutrino mixing with the magnetized iron calorimeter (ICAL) at the India-based Neutrino Observatory (INO), using atmospheric neutrinos as a source.

Updated fit to three neutrino mixing: status of leptonic CP violation [PDF]
Journal of High Energy Physics, 2014 We present a global analysis of solar, atmospheric, reactor and accelerator neutrino data in the framework of three-neutrino oscillations based on data available in summer 2014.

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 ...
