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-

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.

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.

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

Deviations in tribimaximal mixing from sterile neutrino sector
Nuclear Physics B, 2016 We explore the possibility of generating a non-zero Ue3 element of the neutrino mixing matrix from tribimaximal neutrino mixing by adding a light sterile neutrino to the active neutrinos.

Trimaximal neutrino mixing from modular A4 invariance with residual symmetries
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

Corrections to scaling neutrino mixing: Non-zero θ13,δCP and baryon asymmetry
Nuclear Physics B, 2015 We study a very specific type of neutrino mass and mixing structure based on the idea of Strong Scaling Ansatz (SSA) where the ratios of neutrino mass matrix elements belonging to two different columns are equal.

Discrete flavour symmetries, neutrino mixing and leptonic CP violation
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
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

European Physical Journal C: Particles and Fields, 2017 We study the discovery potential for the mixing of heavy isospin-singlet neutrinos in extensions of the Tokai-to-Kamioka (T2K) experiment, the Tokai-to-Hyper-Kamiokande (T2HK), the Tokai-to-Hyper-Kamiokande-to-Korea (T2HKK) with a Korea detector with ...
