Abstract
We report on a search for the pair production of second generation scalar leptoquarks ( LQ 2 ) in p p ¯ collisions at the center-of-mass energy s = 1.96 TeV , using data corresponding to an integrated luminosity of 294 ± 19 pb −1 recorded with the DØ detector. No evidence for a leptoquark signal in the LQ 2 LQ ¯ 2 → μ q μ q channel has been observed, and upper bounds on the product of cross section times branching fraction were set. This yields lower mass limits of m LQ 2 > 247 GeV / c 2 for β = B ( LQ 2 → μ q ) = 1 and m LQ 2 > 182 GeV / c 2 for β = 1 / 2 . Combining these limits with previous DØ results, the lower limits on the mass of a second generation scalar leptoquark are m LQ 2 > 251 GeV / c 2 and m LQ 2 > 204 GeV / c 2 for β = 1 and β = 1 / 2 , respectively.

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.
