Measurement of the rate of ve + d → p + p + e<sup>-</sup> interactions produced by <sup>8</sup>B solar neutrinos at the sudbury neutrino observatory
Bibliographic record
Abstract
Solar neutrinos from 8B decay have been detected at the Sudbury Neutrino Observatory via the charged current (CC) reaction on deuterium and the elastic scattering (ES) of electrons. The flux of νe’s is measured by the CC reaction rate to be φCC(ve) = 1.75 ± 0.07(stat)+0.12−0.11(syst) ± 0.05(theor) × 106 cm−2s−1. Comparison of φCC(ve) to the Super-Kamiokande Collaboration’s precision value of the flux inferred from the ES reaction yields a 3.3σ difference, assuming the systematic uncertainties are normally distributed, providing evidence of an active non-ve component in the solar flux. The total flux of active 8B neutrinos is determined to be 5.44 ± 0.99 × 106 cm−2s−1. © 2001 The American Physical Society.

How this classification was reachedexpand
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.
