Constraints on neutrino parameters from neutral-current solar neutrino measurements
Bibliographic record
Abstract
We generalize the pull approach to define the ${\ensuremath{\chi}}^{2}$ function to the analysis of the data with correlated statistical errors. We apply this method to the analysis of the Sudbury Neutrino Collaboration data obtained in the salt phase. In the global analysis of all the solar neutrino and KamLAND data we find the best fit (minimum ${\ensuremath{\chi}}^{2})$ values of neutrino parameters to be ${\mathrm{tan}}^{2}{\ensuremath{\theta}}_{12}\ensuremath{\sim}0.42$ and $\ensuremath{\delta}{m}_{12}^{2}\ensuremath{\sim}7.1\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}{\mathrm{eV}}^{2}.$ We confirm that the maximal mixing is strongly disfavored while the bounds on $\ensuremath{\delta}{m}_{12}^{2}$ are significantly strengthened.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
