Search for first-generation scalar leptoquarks in (<i>pp</i> collisions at√<i>s</i> = 1.96 TeV
Bibliographic record
Abstract
We report on a search for pair production of first-generation scalar leptoquarks (LQ) in pp̅ collisions at √s = 1.96 TeV using an integrated luminosity of 252 pb-1 collected at the Fermilab Tevatron collider by the D0 detector. We observe no evidence for LQ production in the topologies arising from LQL̅Q̅ → ℯqℯq and LQL̅Q̅ → ℯqνq, and derive 95% C.L. lower limits on the LQ mass as a function of β, where β is the branching fraction for LQ → ℯq. The limits are 241 and 218 GeV/c2 for β = 1 and 0.5, respectively. These results are combined with those obtained by √s = 1.8 TeV, which increases these LQ mass limits to 256 and 234 GeV/c2.

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.
