CLNS 93/1242 CLEO 93-16 Measurement of the absolute branching fraction for
Bibliographic record
Abstract
Using 1.79 fb \\Gamma1 of data recorded by the CLEO II detector we have measured the absolute branching fraction for D 0 ! K \\Gamma + . The angular correlation between the + emitted in the decay D + ! D 0 + , and the jet direction in e + e \\Gamma ! cc events, is used to determine the total number of inclusive D 0 mesons produced from this source. The subsequent reconstruction of the decay chain D + ! D 0 + , D 0 ! K \\Gamma + , allows a measurement of the absolute D 0 ! K \\Gamma + branching fraction. Correcting for decay radiation in the final state, we find B(D 0 ! K \\Gamma + ) = [3:95 \\Sigma 0:08(stat.)\\Sigma0:17(syst.)]%.

K \\Gamma + ) is extremely important for B and D meson experimental ...

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; a candidate call from one teacher head, not a consensus.
