Abstract
We present the first measurement of the integrated forward-backward charge asymmetry in top-quark--top-antiquark pair ($t\overline{t}$) production in proton-antiproton ($p\overline{p}$) collisions in the $\mathrm{\text{lepton}}+\mathrm{\text{jets}}$ final state. Using a $b$-jet tagging algorithm and kinematic reconstruction assuming $t\overline{t}+X$ production and decay, a sample of $0.9\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data, collected by the D0 experiment at the Fermilab Tevatron Collider, is used to measure the asymmetry for different jet multiplicities. The result is also used to set upper limits on $t\overline{t}+X$ production via a ${Z}^{\ensuremath{'}}$ resonance.

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
