Abstract
A search for direct production of scalar bottom quarks ($\stackrel{\texttildelow{}}{b}$) is performed with $310\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of data collected by the D0 experiment in $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ at the Fermilab Tevatron Collider. The topology analyzed consists of two $b$ jets and an imbalance in transverse momentum due to undetected neutralinos (${\stackrel{\texttildelow{}}{\ensuremath{\chi}}}_{1}^{0}$), with ${\stackrel{\texttildelow{}}{\ensuremath{\chi}}}_{1}^{0}$ assumed to be the lightest supersymmetric particle. We find the data consistent with standard model expectations, and set a 95% C.L. exclusion domain in the (${m}_{\stackrel{\texttildelow{}}{b}}$, ${m}_{{\stackrel{\texttildelow{}}{\ensuremath{\chi}}}_{1}^{0}}$) mass plane, improving significantly upon the results from run I of the Tevatron.

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.
