Abstract

The Sudbury Neutrino Observatory (SNO) has measured day and night solar neutrino energy spectra and rates. For charged current events, assuming an undistorted ${}^{8}\mathrm{B}$ spectrum, the night minus day rate is $14.0%\ifmmode\pm\else\textpm\fi{}6.3{%}_{\ensuremath{-}1.4}^{+1.5}%$ of the average rate. If the total flux of active neutrinos is additionally constrained to have no asymmetry, the ${\ensuremath{\nu}}_{e}$ asymmetry is found to be $7.0%\ifmmode\pm\else\textpm\fi{}4.9{%}_{\ensuremath{-}1.2}^{+1.3}%$. A global solar neutrino analysis in terms of matter-enhanced oscillations of two active flavors strongly favors the large mixing angle solution.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
