Abstract

fetched live from OpenAlex

The ratio of the proton's elastic electromagnetic form factors, ${G}_{{E}_{p}}{/G}_{{M}_{p}}$, was obtained by measuring ${P}_{t}$ and ${P}_{\ensuremath{\ell}}$, the transverse and the longitudinal recoil proton polarization, respectively. For elastic $\stackrel{\ensuremath{\rightarrow}}{e}p\ensuremath{\rightarrow}e\stackrel{\ensuremath{\rightarrow}}{p}$, ${G}_{{E}_{p}}{/G}_{{M}_{p}}$ is proportional to ${P}_{t}{/P}_{\ensuremath{\ell}}$. Simultaneous measurement of ${P}_{t}$ and ${P}_{\ensuremath{\ell}}$ in a polarimeter provides good control of the systematic uncertainty. The results for the ratio ${G}_{{E}_{p}}{/G}_{{M}_{p}}$ show a systematic decrease as ${Q}^{2}$ increases from 0.5 to $3.5{\mathrm{GeV}}^{2}$, indicating for the first time a definite difference in the spatial distribution of charge and magnetization currents in the proton.

Full frame distilled prediction

Teacher imitation

Not 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.
