Search for Sterile Neutrinos Mixing with Muon Neutrinos in MINOS.
We report results of a search for oscillations involving a light sterile neutrino over distances of 1.04 and 735 km in a ν_{μ}-dominated beam with a peak energy of 3 GeV. The data, from an exposure of 10.56×10^{20} protons on target, are analyzed using a phenomenological model with one sterile neutrino. We constrain the mixing parameters θ_{24} and Δm_{41}^{2} and set limits on parameters of th...
متن کاملTwo–mixing Texture for Three Active Neutrinos *
The conjecture that among three massive neutrinos ν1 , ν2 , ν3 there is no direct mixing between ν1 and ν3 leads to a two–mixing texture for three active neutrinos νe , νμ , ντ . This texture, much discussed previously, is neatly consistent with the observed deficits of solar νe’s and atmospheric νμ’s, but (without extra mixing with at least one sterile neutrino νs) predicts no LSND effect for ...
متن کاملSolar Neutrinos and Lepton Mixing
With latest experimental data the solar neutrino problem enters new phase when crucial aspects of the problem can be formulated in an essentially (solar) model independent way. Original neutrino fluxes can be considered as free parameters to be found from the solar neutrino experiments. Resonance flavour conversion gives the best fit of all experimental results. Already existing data allow one ...
متن کاملA New Mixing Rule for Mixtures of Hard Spheres
A mixing rule for the mixtures of hard-spheres is presented which can be reduced to the standard van der Waals mixing rule at low densities. The effectiveness of the mixing rule for the size and energy parameters of lennard-Jones fluid are examined by combining them with an equation of state to calculate thermodynamic properties. The results of calculation are compared with the molecular dy...
متن کاملConstraints on Exotic Mixing of Three Neutrinos
Exotic explanations are considered for atmospheric neutrino observations. Our analysis includes matter effects and the mixing of all three neutrinos under the simplifying assumption of only one relevant mixing scale. Constraints from accelerator, reactor and solar neutrinos are included. We find that the proposed mixing mechanisms based on violations of Lorentz invariance or on violations of th...
