Abstract
We describe searches for B meson decays to the charmless vector-vector final states ÏÏ and ÏÏ with 471Ã106BBÌ pairs produced in e+e- annihilation at s=10.58GeV using the BABAR detector at the PEP-II collider at the SLAC National Accelerator Laboratory. We measure the branching fraction B(B0âÏÏ)=(1.2±0.3-0.2+0.3)Ã10- 6, where the first uncertainty is statistical and the second is systematic, corresponding to a significance of 4.4 standard deviations. We also determine the upper limit B(B0âÏÏ) < 0.7Ã10-6 at 90% confidence level. These measurements provide the first evidence for the decay B0âÏÏ, and an improvement of the upper limit for the decay B0âÏÏ. © 2014 American Physical Society.

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 it
