Abstract
We report results from a study of events with a leading antiproton of beam momentum fraction $0.905<{x}_{F}<0.965$ and 4-momentum transfer squared $|t|<3{\mathrm{GeV}}^{2}$ produced in $\overline{p}p$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1800\mathrm{GeV}$ at the Fermilab Tevatron collider. Approximately $2%$ of the events contain two jets of transverse energy ${E}_{T}^{\mathrm{jet}}>7\mathrm{GeV}$. Using the dijet events, we evaluate the diffractive structure function of the antiproton and compare it with expectations based on results obtained in diffractive deep inelastic scattering experiments at the DESY $\mathrm{ep}$ collider HERA.

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.
