Abstract
We report measurements of the inclusive transverse momentum (${p}_{T}$) distribution of centrally produced ${K}_{S}^{0}$, ${K}^{\ensuremath{\star}\ifmmode\pm\else\textpm\fi{}}(892)$, and ${\ensuremath{\phi}}^{0}(1020)$ mesons up to ${p}_{T}=10\text{ }\text{ }\mathrm{GeV}/c$ in minimum bias events, and ${K}_{S}^{0}$ and ${\ensuremath{\Lambda}}^{0}$ particles up to ${p}_{T}=20\text{ }\text{ }\mathrm{GeV}/c$ in jets with transverse energy between 25 and 160 GeV in $p\overline{p}$ collisions. The data were taken with the CDF II detector at the Fermilab Tevatron at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$. We find that as ${p}_{T}$ increases, the ${p}_{T}$ slopes of the three mesons (${K}_{S}^{0}$, ${K}^{\ensuremath{\star}\ifmmode\pm\else\textpm\fi{}}$, and $\ensuremath{\phi}$) are similar. And using our previous ${\ensuremath{\Lambda}}^{0}$ results from minimum bias events, we show that the ratio of ${\ensuremath{\Lambda}}^{0}$ to ${K}_{S}^{0}$ as a function of ${p}_{T}$ in minimum bias events becomes similar to the fairly constant ratio in jets at ${p}_{T}\ensuremath{\sim}5\text{ }\text{ }\mathrm{GeV}/c$. This suggests that the particles with ${p}_{T}\ensuremath{\gtrsim}5\text{ }\text{ }\mathrm{GeV}/c$ in minimum bias events are from ``soft'' jets, and that the ${p}_{T}$ slope of particles in jets is insensitive to light quark flavor ($u$, $d$, or $s$) and to the number of valence quarks. We also find that for ${p}_{T}\ensuremath{\lesssim}4\text{ }\text{ }\mathrm{GeV}$ relatively more ${\ensuremath{\Lambda}}^{0}$ baryons are produced in minimum bias events than in jets.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
