Abstract
The $^{1}\mathrm{H}(e,{e}^{\ensuremath{'}}{\ensuremath{\pi}}^{+})n$ cross section was measured at four-momentum transfers of ${Q}^{2}=1.60$ and $2.45\text{ }\text{ }{\mathrm{GeV}}^{2}$ at an invariant mass of the photon nucleon system of $W=2.22\text{ }\text{ }\mathrm{GeV}$. The charged pion form factor (${F}_{\ensuremath{\pi}}$) was extracted from the data by comparing the separated longitudinal pion electroproduction cross section to a Regge model prediction in which ${F}_{\ensuremath{\pi}}$ is a free parameter. The results indicate that the pion form factor deviates from the charge-radius constrained monopole form at these values of ${Q}^{2}$ by one sigma, but is still far from its perturbative quantum chromodynamics prediction.

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
