Branching Fraction and CP Asymmetries of B0→K0SK0SK0S
Bibliographic record
Abstract
We present measurements of the branching fraction and time-dependent CP-violating asymmetries in B-0-> (KSKSKS0)-K-0-K-0 decays based on 227x10(6) Upsilon(4S)-> B (B) over bar decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We obtain a branching fraction of (6.9(-0.8)(+0.9)+/- 0.6)x10(-6), and CP asymmetries C=-0.34(-0.25)(+0.28)+/- 0.05 and S=-0.71(-0.32)(+0.38)+/- 0.04, where the first uncertainties are statistical and the second systematic.

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.
