Abstract

fetched live from OpenAlex

The Standard Model (SM) represents our best description of the subatomic world and has been very successful in explaining how elementary particles interact under the influence of the fundamental forces.Despite its far reaching success in describing the building blocks of matter, the SM is still incomplete; falling short to explain dark matter, baryogenesis, neutrino masses and much more.The E36 experiment conducted at J-PARC in Japan, allows for sensitivity to search for light U (1) gauge bosons, in the muonic K + decay channel.Such U (1) bosons could be associated with dark matter or explain established muon-related anomalies such as the muon g -2 value, and perhaps the proton radius puzzle.A realistic simulation study was employed for these rare searches in a mass range of 20 MeV to 100 MeV.Preliminary results of the upper limits for the A branching ratio Br(A ) extracted at 95% CL, will be presented.

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.
