Abstract
We investigate the status of the neutrino decay solution to the solar neutrino problem in the context of the recent results from Sudbury Neutrino Observatory (SNO). We present the results of global $\\chi^2$-analysis for both two and three generation cases with one of the mass states being allowed to decay and include the effect of both decay and mixing. We find that the Large Mixing Angle (LMA) region which is the currently favoured solution of the solar neutrino problem is affected significantly by decay. We obtain bounds on the decay constant $\\alpha$ in this region which implies a rest frame life time $\\tau_0/m > 1.5 \\times 10^{-5}$ sec/eV for the unstable neutrino state. We present the allowed areas in the $\\Delta m^2-\\tan^2\\theta$ plane for different allowed values of $\\alpha$ and examine how these areas change with the inclusion of decay. Finally we show that the forthcoming neutral currrent data from SNO can further constrain the allowed values of $\\alpha$, $\\Delta m^2$ and $\\tan^2\\theta$.

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; both teacher heads agree on what is shown here.
