Abstract
We describe a general search for resonances decaying to a neutral $e\ensuremath{\mu}$ final state in $p\overline{p}$ collisions at a center-of-mass energy of 1.96 TeV. Using a data sample representing $344\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of integrated luminosity recorded by the Collider Detector at Fermilab II experiment, we compare standard model predictions with the number of observed events for invariant masses between 50 and $800\text{ }\text{ }\mathrm{GeV}/{c}^{2}$. Finding no significant excess (5 events observed vs $7.7\ifmmode\pm\else\textpm\fi{}0.8$ expected for ${M}_{e\ensuremath{\mu}}>100\text{ }\text{ }\mathrm{GeV}/{c}^{2}$), we set limits on sneutrino and ${Z}^{\ensuremath{'}}$ masses as functions of lepton family number violating couplings.

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.
