Abstract
We report on a search for the flavor-changing neutral current decay D0→µ+µ- in pp̅ collisions at √s =1.96 TeV using 65 pb-1 of data collected by the CDF II experiment at the Fermilab Tevatron Collider. A displaced-track trigger selects long-lived D0 candidates in the D0→µ+µ- search channel, the kinematically similar D0→ π+ π- channel used for normalization, the Cabibbo-favored D0→ K-π+ channel used to optimize the selection criteria in an unbiased manner, and their charge conjugates. Finding no signal events in the D0→µ+µ- search window, we set an upper limit on the branching fraction Ɓ(D0→µ+µ-)<=2.5×10-6 (3.3×10-6) at the 90% (95%) confidence level.

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
