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

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.

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 ...

Bound on 3+1 Active-Sterile Neutrino Mixing from the First Four-Week Science Run of KATRIN. [PDF]
Physical Review Letters, 2020 We report on the light sterile neutrino search from the first four-week science run of the KATRIN experiment in 2019. Beta-decay electrons from a high-purity gaseous molecular tritium source are analyzed by a high-resolution MAC-E filter down to 40 eV ...

Phenomenology of Trimaximal Mixing with One Texture Equality
Advances in High Energy Physics, 2022 We study neutrino mass matrices with one texture equality and the neutrino mixing matrix having either its first (TM1) or second (TM2) column identical to that of the tribimaximal mixing matrix.
