Abstract
A phenomenological $pn\ensuremath{\rightarrow}pp{\ensuremath{\pi}}^{\ensuremath{-}}$ model of $A(p,{\ensuremath{\pi}}^{\ensuremath{-}})B$ reactions is developed that incorporates the spin dependence of the former reaction. The model development follows closely that of the $pp\ensuremath{\rightarrow}d{\ensuremath{\pi}}^{+}$ model for $A(p,{\ensuremath{\pi}}^{+})C$ reactions. Predictions of the analyzing powers and differential cross sections for the $(p,{\ensuremath{\pi}}^{\ensuremath{-}})$ reaction on ${}^{13}$C at 200 MeV are presented and discussed. Calculated differential cross sections describe reasonably well the shape of the experimental data, although the predicted strengths vary considerably. Model predictions of the analyzing powers are in general agreement with the data. Nuclear structure amplitudes are obtained from a no-core multi-$\ensuremath{\hbar}\ensuremath{\omega}$ shell model. Sensitivities of the observables to the nuclear structure details and also the amplitudes of the primary $pn\ensuremath{\rightarrow}pp{\ensuremath{\pi}}^{\ensuremath{-}}$ reaction are investigated.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
