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 ...

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.

Neutrino mixing and neutrino telescopes [PDF]
Journal of Cosmology and Astroparticle Physics, 2007 Measuring flux ratios of ultra-high energy neutrinos is an alternative method to determine the neutrino mixing angles and the CP phase delta. We conduct a systematic analysis of the neutrino mixing probabilities and of various flux ratios measurable at neutrino telescopes.

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.

Trimaximal neutrino mixing from scotogenic A4 family symmetry
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.

Neutrino masses and mixing [PDF]
Nuclear Physics B - Proceedings Supplements, 1999 I review the status of neutrino masses and mixings in the light of the solar and atmospheric neutrino data. The result from the LSND experiment and the possible role of neutrinos as hot dark matter are also included. I also discuss the simplest schemes proposed to reconcile these data which include a light sterile neutrino in addition to the three ...

Neutrino mixing and RK anomaly in U(1)X models: a bottom-up approach [PDF]
Journal of High Energy Physics, 2017 We identify a class of U(1)X models which can explain the RK anomaly and the neutrino mixing pattern, by using a bottom-up approach. The different X-charges of lepton generations account for the lepton universality violation required to explain RK .

Physics Letters B, 2010 Three-neutrino mixing in matter is studied through a set of evolution equations which are based on a rephasing invariant parametrization. Making use of the known properties of measured neutrino parameters, analytic, approximate, solutions are obtained. Their accuracy is confirmed by comparison with numerical integration of these equations. The results,

On the role of neutrino mixing in accelerated proton decay [PDF]
, 2018 The inverse beta decay of accelerated protons has been analyzed both in the laboratory frame (where the proton is accelerated) and in the comoving frame (where the proton is at rest and interacts with the Fulling-Davies-Unruh thermal bath of electrons ...
