Abstract

fetched live from OpenAlex

We perform a static calculation of decay widths for radiative transitions of mesons within the conventional picture of photon emission by a confined quark and (or) antiquark. As the calculation based on the moderate momentum transfer allows some amount of uncertainty to creep into the model predictions, we further apply the model for a more realistic calculation beyond the static approximation, taking into account some momentum-dependent effects due to the recoil of the daughter meson. The results obtained for the decay widths of radiative transitions of light mesons are improved and are in good agreement with the experimental values. The predictions on the decay rates of heavy mesons are also affected and are comparable with those of other model predictions.

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. 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.
