Abstract
We present the results of a search for the flavor changing neutral current decay B s 0 → μ + μ − using 6.1 fb − 1 of p p ¯ collisions at s = 1.96 TeV collected by the D0 experiment at the Fermilab Tevatron Collider. The observed number of B s 0 candidates is consistent with background expectations. The resulting upper limit on the branching fraction is B ( B s 0 → μ + μ − ) < 5.1 × 10 − 8 at the 95% C.L. This limit is a factor of 2.4 better than that of the previous D0 analysis and the best limit to date.

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
