Abstract

fetched live from OpenAlex

An upper bound to the supernova relic neutrino background from all past type II supernovae is obtained using observations of the universal metal enrichment history. We show that an unambiguous detection of these relic neutrinos by the SuperKamiokande detector is unlikely. We also analyze the event rate in the Sudbury Neutrino Observatory (where coincident neutrons from ${\overline{\ensuremath{\nu}}}_{e}\stackrel{\ensuremath{\rightarrow}}{D}{\mathrm{nne}}^{+}$ might enhance background rejection), and arrive at the same conclusion. If the relic neutrino flux should be observed to exceed our upper bound and if the observations of the metal enrichment history (for $z<1)$ are not in considerable error, then either the type II supernova rate does not track the metal enrichment history or some mechanism may be responsible for transforming ${\overline{\ensuremath{\nu}}}_{\ensuremath{\mu},\ensuremath{\tau}}\ensuremath{\rightarrow}{\overline{\ensuremath{\nu}}}_{e}.$

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.

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.
