Viable Twin Cosmology from Neutrino Mixing [PDF]
, 2017 Twin Higgs models solve the little hierarchy problem without introducing new colored particles, however they are often in tension with measurements of the radiation density at late times.

First Constraints on the Complete Neutrino Mixing Matrix with a Sterile Neutrino. [PDF]
Physical Review Letters, 2016 Neutrino oscillation models involving one extra mass eigenstate beyond the standard three (3+1) are fit to global short baseline experimental data and the recent IceCube ν_{μ}+ν[over ¯]_{μ} disappearance search result. We find a best fit of Δm_{41}^{2}=1.

Neutrino mixing and cosmology [PDF]
Nuclear Physics B - Proceedings Supplements, 2005 We review the consequences of neutrino mixing in the early universe. For both active-sterile mixing or mixing between three active neutrinos only, the consequences of oscillations depend crucially upon the size of the universe's lepton number (relic neutrino asymmetry.)

The Nature of Massive Neutrinos
Advances in High Energy Physics, 2013 The compelling experimental evidences for oscillations of solar, reactor, atmospheric, and accelerator neutrinos imply the existence of 3-neutrino mixing in the weak charged lepton current.

Addressing neutrino mixing models with DUNE and T2HK [PDF]
, 2017 We consider schemes of neutrino mixing arising within the discrete symmetry approach to the well-known flavour problem. We concentrate on $$3\nu $$3ν mixing schemes in which the cosine of the Dirac CP violation phase $$\delta _{\mathrm {CP}}$$δCP ...

Radiative magnification of neutrino mixings and a natural explanation of the neutrino anomalies [PDF]
, 2000 We show that the neutrino mixing pattern with the large mixing required for the atmospheric neutrino problem and the small mixing angle MSW solution for the solar neutrino problem can be naturally generated through radiative magnification, even though ...

Modelling tribimaximal neutrino mixing [PDF]
Physical Review D, 2009 We model tri-bimaximal lepton mixing from first principles in a way that avoids the problem of the vacuum alignment characteristic of such models. This is achieved by using a softly broken A4 symmetry realized with an isotriplet fermion, also triplet under A4. No scalar A4-triplet is introduced.

Locating the core-mantle boundary using oscillations of atmospheric neutrinos
Journal of High Energy Physics, 2023 Atmospheric neutrinos provide a unique avenue to explore the internal structure of Earth based on weak interactions, which is complementary to seismic studies and gravitational measurements.

Cobimaximal neutrino mixing from A4 and its possible deviation [PDF]
, 2017 It has recently been shown that the phenomenologically successful pattern of cobimaximal neutrino mixing ( , , and ) may be achieved in the context of the non-Abelian discrete symmetry A4, if the neutrino mass matrix is diagonaized by an orthogonal ...

Numerical estimate of minimal active-sterile neutrino mixing
EPJ Web of Conferences, 2018 Seesaw mechanism constrains from below mixing between active and sterile neutrinos for fixed sterile neutrino masses. Signal events associated with sterile neutrino decays inside a detector at fixed target experiment are suppressed by the mixing angle to
