Search for CP violation and a measurement of the relative branching fraction in D+âK-K+Ï+ decays
Bibliographic record
Abstract
We report on a search for the CP asymmetry in the singly Cabibbo-suppressed decays D+âK-K+Ï+ and in the resonant decays D+âÏ+ and D+âKÌ*0K+ based on a data sample of 79.9fb-1 recorded by the BABAR detector. We use the Cabibbo-favored Ds+âK-K+Ï+ branching fraction as normalization in the measurements to reduce systematic uncertainties. The CP asymmetries obtained are ACP(K-K+ϱ)=(1.4±1.0(stat)±0. 8(syst))Ã10-2, ACP(ϱ)=(0.2±1.5(stat)±0.6(syst)) Ã10-2, and ACP(KÌ*0K±)=(0.9±1.7(stat)±0. 7(syst))Ã10-2. The relative branching fraction Î(D+âK-K+Ï+)/ Î(D+âK-Ï+Ï+) is also measured and is found to be (10.7±0.1(stat)±0.2(syst))Ã10-2. © 2005 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.
