Abstract
The E885 Collaboration utilized the $1.8 \mathrm{GeV}{/cK}^{\ensuremath{-}}$ beam line at the Alternating Gradient Synchrotron (AGS) to accumulate greater than 10 times the world's existing data sample of ${(K}^{\ensuremath{-}}{,K}^{+})$ events on carbon. A total of about $3\ifmmode\times\else\texttimes\fi{}{10}^{5} {(K}^{\ensuremath{-}}{,K}^{+})$ events were collected and analyzed. $\ensuremath{\Xi}$ hypernuclear states are expected to be produced through the reaction ${K}^{\ensuremath{-}}{+}^{12}\stackrel{\ensuremath{\rightarrow}}{C}{K}^{+}{+}_{\ensuremath{\Xi}}^{12}\mathrm{Be}.$ A signal could also result from direct production of ${}_{\ensuremath{\Lambda}}^{11}\mathrm{Be}+\ensuremath{\Lambda}$ without a distinct $\ensuremath{\Xi}$ intermediate state. The measured missing-mass spectrum indicates the existence of a signal below the threshold for free ${\ensuremath{\Xi}}^{\ensuremath{-}}$ production that cannot be explained by background or effects of limited resolution. Although the resolution was not sufficient to resolve discrete hypernuclear states, the excess of events in the region of missing mass, kinematically inaccessible in free ${\ensuremath{\Xi}}^{\ensuremath{-}}$ production, can be compared with theoretical predictions for ${}_{\ensuremath{\Xi}}^{12}\mathrm{Be}$ production. Reasonable agreement between the data and theory is achieved by assuming a $\ensuremath{\Xi}$-nucleus potential well depth ${\mathrm{V}}_{0\ensuremath{\Xi}}$ of about 14 MeV within the Woods-Saxon prescription.

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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
