Abstract

fetched live from OpenAlex

Analyzing ÇðnSÞ decays acquired with the CLEO detector operating at the CESR e þ e À collider, we measure for the first time the product branching fractions B½ÇðnSÞ !bJ ððn À 1ÞPÞB½ bJ ðn À 1ÞPÞ !X i for n ¼ 2 and 3, where X i denotes, for each i, one of the 14 exclusive light-hadron final states for which we observe significant signals in both bJ ð1PÞ and bJ ð2PÞ decays.We also determine upper limits for the electric dipole (E1) transitions Çð3SÞ !bJ ð1PÞ.

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.
