Search for bâu transitions in B-â[K+Ï-Ï0]DK-
Bibliographic record
Abstract
We search for decays of a B meson into a neutral D meson and a charged kaon, with the D meson decaying into a charged kaon, a charged pion, and a neutral pion. This final state can be reached through the bâc transition B-âD0K- followed by the doubly Cabibbo-suppressed D0âK+Ï-Ï0, or the bâu transition B-âDÌ0K- followed by the Cabibbo-favored DÌ0âK+Ï-Ï0. The interference of these two amplitudes is sensitive to the angle γ of the unitarity triangle. We present results based on 226Ã106 e+e-âÎ¥(4S)âBBÌ events collected with the BABAR detector at SLAC. We find no significant evidence for these decays and we set a limit RADSâ¡Î([K+Ï-Ï0]DK-)+Î([K-Ï+Ï0] DK+) Î([K+Ï-Ï0]DK+)+Î([K-Ï+Ï0] DK-) < 0.039 at 95% confidence level, which we translate with a Bayesian approach into rBâ¡|A(B- âDÌ0K-)/A(B-âD0K-)| < 0.19 at 95% confidence level. © 2007 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.
