Alberta Thy 20-06 Coulomb force correction to the decay b → c¯cs in the threshold
Bibliographic record
Abstract
We study the physical origins of the O(αs) and O(α2 s) corrections to the ¯c − s current in the decay b → c¯cs at the threshold region δ = (Mb−2mc)/Mb ≪ 1. We obtain the corrections which are produced by the Coulomb force between the anti-charm and strange quarks. The Coulomb corrections CFπ 2 at O(αs) and −C 2 F π2 ln δ at O(α 2 s) account for 300 % and 120 % of the corresponding terms in the Abelian-type perturbative corrections respectively. We also check that the Wilson coefficient for the anomalous dimension of the ¯c−s current reproduces the leading and the next-to-leading logarithmic terms in the perturbative corrections.

Full frame distilled prediction
Teacher imitationNot 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.
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; both teacher heads agree on what is shown here.
