On Deviations from Bimaximal Neutrino Mixing [PDF]

, 2004
The PMNS neutrino mixing matrix U_{PMNS} is in general a product of two unitary matrices U_{lep} and U_{\nu} arising from the diagonalization of the charged lepton and neutrino mass matrices, U_{PMNS} = U^{\dagger}_{lep} U_{\nu}. Assuming that U_{\nu} is

Neutrino mixing in matter

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,

Theoretical Aspects of Neutrino Oscillation [PDF]

, 2001
I review some aspects concerning the physics of neutrino mixing and oscillations. I discuss in some detail the physical neutrino oscillations parameter space in the case of two and three family mixing, and briefly describe the current knowledge of ...

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

Neutrino masses and neutrino mixing

Nuclear Physics B - Proceedings Supplements, 2006
We review the current (summer 2005) status of neutrino mass and mixing parameters, as emerging from a phenomenological analysis of world neutrino oscillation and non-oscillation data, performed within the standard three-neutrino mixing framework.

Majorana neutrino mixing [PDF]

Journal of Physics G: Nuclear and Particle Physics, 2006
The most plausible see-saw explanation of the smallness of the neutrino masses is based on the assumption that total lepton number is violated at a large scale and neutrinos with definite masses are Majorana particles. In this review we consider in details difference between Dirac and Majorana neutrino mixing and possibilities of revealing Majorana ...

Search for heavy neutrinos mixing with tau neutrinos [PDF]

Physics Letters B, 2001
We report on a search for heavy neutrinos ($\nus$) produced in the decay $D_s\to \nus$ at the SPS proton target followed by the decay $\nudecay$ in the NOMAD detector. Both decays are expected to occur if $\nus$ is a component of $ _ $.\ From the analysis of the data collected during the 1996-1998 runs with $4.1\times10^{19}$ protons on target, a ...

Heavy neutrino mixing in the T2HK, the T2HKK and an extension of the T2HK with a detector at Oki Islands

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 ...

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.)

Impact of an eV-mass sterile neutrino on the neutrinoless double-beta decays: A Bayesian analysis

Nuclear Physics B, 2019
To quantitatively assess the impact of an eV-mass sterile neutrino on the neutrinoless double-beta (0νββ) decays, we calculate the posterior probability distribution of the relevant effective neutrino mass |mee′| in the (3+1)ν mixing scenario, following ...
