Measurement of [Formula Presented] and [Formula Presented] production in [Formula Presented] meson decays and from continuum [Formula Presented] annihilation at [Formula Presented] GeV
Bibliographic record
Abstract
New measurements of (Formula presented) and (Formula presented) meson production rates from B decays and from (Formula presented) continuum events near the (Formula presented) resonance are presented. Using 20.8 (Formula presented) of data on the (Formula presented) resonance and 2.6 (Formula presented) off-resonance, we find the inclusive branching fractions (Formula presented) and (Formula presented) where the first error is statistical, the second is systematic, and t he third is due to the (Formula presented) branching fraction uncertainty. The production cross sections (Formula presented) and (Formula presented) are measured at center-of-mass energies about 40 MeV below the (Formula presented) mass. The branching fractions (Formula presented) and (Formula presented) are determined from the (Formula presented) momentum spectra. The mass difference (Formula presented) is also measured. © 2002 The American Physical Society.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
