First Constraints on the Complete Neutrino Mixing Matrix with a Sterile Neutrino. [PDF]
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.

An Overview of Neutrino Mixing [PDF]
We present a concise review of the recent important experimental developments on neutrino mixing (hints for sterile neutrinos, large $ _{13}$, possible non maximal $ _{23}$, approaching sensitivity on $ _{CP}$) and their implications on models of neutrino mixing. The new data disfavour many models but the surviving ones still span a wide range going

A revolution in our understanding of the neutrino sector is underway, driven by observations that are interpreted in terms of changes in neutrino flavors as they propagate. Since neutrino oscillations occur only if neutrinos are massive, these phenomena indicate physics beyond the Standard Model.

Addressing neutrino mixing models with DUNE and T2HK [PDF]
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 ...

The Nature of Massive Neutrinos
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.

Viable Twin Cosmology from Neutrino Mixing [PDF]
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.

NEUTRINO MASSES AND MIXINGS [PDF]
We propose a novel theoretical understanding of neutrino masses and mixings, which is attributed to the left–right symmetric feature of the regularized standard model at short distances. We try to explain the smallness of Dirac neutrino masses and the decoupling of the right-handed neutrino as a free particle.

Numerical estimate of minimal active-sterile neutrino mixing
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

Cobimaximal neutrino mixing from A4 and its possible deviation [PDF]
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 ...
