Abstract
We have used a sample of $\ensuremath{\gamma}+3$ jets events collected by the D0 experiment with an integrated luminosity of about $1\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ to determine the fraction of events with double parton scattering (${f}_{\mathrm{DP}}$) in a single $p\overline{p}$ collision at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$. The DP fraction and effective cross section (${\ensuremath{\sigma}}_{\mathrm{eff}}$), a process-independent scale parameter related to the parton density inside the nucleon, are measured in three intervals of the second (ordered in ${p}_{T}$) jet transverse momentum ${p}_{T}^{\mathrm{jet}2}$ within the range $15\ensuremath{\le}{p}_{T}^{\mathrm{jet}2}\ensuremath{\le}30\text{ }\text{ }\mathrm{GeV}$. In this range, ${f}_{\mathrm{DP}}$ varies between $0.23\ensuremath{\le}{f}_{\mathrm{DP}}\ensuremath{\le}0.47$, while ${\ensuremath{\sigma}}_{\mathrm{eff}}$ has the average value ${\ensuremath{\sigma}}_{\mathrm{eff}}^{\mathrm{ave}}=16.4\ifmmode\pm\else\textpm\fi{}0.3(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}2.3(\mathrm{syst})\text{ }\text{ }\mathrm{mb}$.

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.
