Abstract

fetched live from OpenAlex

The Sudbury Neutrino Observatory (SNO) is an imaging water Cherenkov detector. Its one kiloton heavy water core provides a unique means for an electron antineutrino search via the charged current reaction νe + d → e + + n + n. The reaction signature are two- and three-fold coincidence events which allow for rigorous background rejection. Hence, SNO is able to reach high electron antineutrino sensitivity. The appearance of electron antineutrinos is a smoking gun for spin flavour precession models which require neutrinos to have a magnetic moment. Furthermore, observation of a significant solar antineutrino flux could be indicative of CPT violation in the neutrino sector. A limit on the antineutrino flux sets an upper limit on the thermal power of a hypothesized geo-fission reactor at the center of the Earth.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
