Abstract

fetched live from OpenAlex

The Sudbury Neutrino Observatory (SNO) is an imaging water Cherenkov detector. It has detected solar neutrinos from the decay of B via the charged current (CC) and neutral current (NC) reactions on deuterium and by the elastic scattering (ES) of electrons. While the CC reaction is exclusively sensitive to νe, the NC reaction is equally sensitive to all types of active neutrinos. In its first phase of running with pure D2O the non-νe component of the NC flux was found to be greater than zero at the 5.3 σ level, providing strong evidence for νe flavor transformation. A global solar neutrino analysis in terms of matterenhanced oscillations favors the Large Mixing Angle (LMA) solution to the solar neutrino problem. In the second phase NaCl has been added to the D2O in order to increase the NC sensitivity. Data acquisition of the salt phase is nearly complete and first results on the NC measurement of this phase are expected to be presented at this conference. The third operational phase of SNO foresees the deployment of neutral current detectors (NCD) inside the D2O volume and hence allows an independent measurement of the NC.

Full frame distilled prediction

Teacher imitation

Not 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.
