Abstract
Solar Neutrinos from the decay of {sup 8}B have been detected at the Sudbury Neutrino Observatory (SNO) by charged current (CC) and neutral current (NC) interactions on deuterium and elastic scattering (ES) of electrons. The SNO data indicate that with the assumption of undistorted {sup 8}B shape, the flux for v{sub e} is {phi}{sub e} = 1.76{sub -0.05}{sup +0.05}(stat.){sub -0.09}{sup +0.09}(syst.) x 10{sup 6} cm{sup -2} s{sup -1} for a kinetic energy threshold of 5 MeV. The non-v{sub e} flux is {phi}{sub {mu}{tau}} = 3.41{sub -0.45}{sup +0.45}(stat.){sub -0.45}{sup +0.48}(syst.) x 10{sup 6} cm{sup -2}s{sup -1}. This provides strong evidence for solar v{sub e} flavor transformation. The day and night solar neutrino energy spectra and rates have also been measured. For CC events, the v{sub e} asymmetry is 14.0% {+-} 6.3%{sub -1.4}{sup +1.5}%. By additionally constraining the total (NC) flux of active neutrinos to have no asymmetry, the v{sub e} asymmetry becomes 7.0% {+-} 4.9%{sub -1.2}{sup +1.3}%. A global solar neutrino analysis strongly favors the Large Mixing Angle (LMA) solution in a two-flavor neutrino oscillation model.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
