Observation of B0âÏc0K*0 and evidence for B+âÏc0K*+
Bibliographic record
Abstract
We present the observation of the decay B0âÏc0K*0 as well as evidence of B+âÏc0K*+, with an 8.9 and a 3.6 standard deviation significance, respectively, using a data sample of 454Ã106 Î¥(4S)âBBÌ decays collected with the BABAR detector at the PEP-II B meson factory located at the Stanford Linear Accelerator Center (SLAC). The measured branching fractions are B(B0âÏc0K*0)=(1.7±0. 3±0.2)Ã10-4 and B(B+âÏc0K*+)=(1.4±0. 5±0.2)Ã10-4, where the first quoted errors are statistical and the second are systematic. We obtain a branching fraction upper limit of B(B+âÏc0K*+) < 2.1Ã10-4 at the 90% confidence level. © 2008 The American Physical Society.

How this classification was reachedexpand
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.
