TLDR
In this article, a tri-bimaximal mixing approach based on other symmetry principles is proposed. But the results of the experiments are limited and in some cases perturbations are required to give better agreement with the data, and use of a minimal approach is illustrated.
Abstract
Possible alternatives to tri-bimaximal mixing are presented based on other symmetry principles, and their predictions for |U e3|, sin 2 θ 12 and sin 2 θ 23 are compared to the present neutrino mixing data. In some cases perturbations are required to give better agreement with the data, and the use of a minimal approach is illustrated. Precise experimental determinations of the mixing parameters will be required to decipher the correct mixing pattern and to pin down the appropriate flavor symmetry.

Evidence for oscillation of atmospheric neutrinos

Y. Fukuda, +124 more
Abstract: We present an analysis of atmospheric neutrino data from a 33.0 kton yr (535-day) exposure of the Super-Kamiokande detector. The data exhibit a zenith angle dependent deficit of muon neutrinos which is inconsistent with expectations based on calculations of the atmospheric neutrino flux. Experimental biases and uncertainties in the prediction of neutrino fluxes and cross sections are unable to explain our observation. The data are consistent, however, with two-flavor ${\ensuremath{ u}}_{\ensuremath{\mu}}\ensuremath{\leftrightarrow}{\ensuremath{ u}}_{\ensuremath{\tau}}$ oscillations with ${sin}^{2}2\ensuremath{\theta}g0.82$ and $5\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}l\ensuremath{\Delta}{m}^{2}l6\ifmmode\times\else\texttimes\fi{}1{0}^{\ensuremath{-}3}\mathrm{eV}{}^{2}$ at 90% confidence level.

Measurement of the solar electron neutrino flux with the Homestake chlorine detector

TL;DR: The Homestake solar neutrino detector as discussed by the authors has been used to measure the flux of neutrinos since 1970, with particular emphasis on the determination of the extraction and counting efficiencies, the key experimental parameters that are necessary to convert the measured 37Ar count rate to the solar Neutrino production rate.
