Abstract

fetched live from OpenAlex

The ratio of the electric and magnetic form factors of the proton ${G}_{{E}_{p}}{/G}_{{M}_{p}}$, which is an image of its charge and magnetization distributions, was measured at the Thomas Jefferson National Accelerator Facility (JLab) using the recoil polarization technique. The ratio of the form factors is directly proportional to the ratio of the transverse to longitudinal components of the polarization of the recoil proton in the elastic $\stackrel{\ensuremath{\rightarrow}}{e}p\ensuremath{\rightarrow}e\stackrel{\ensuremath{\rightarrow}}{p}$ reaction. The new data presented span the range $3.5&lt;{Q}^{2}&lt;5.6{\mathrm{GeV}}^{2}$ and are well described by a linear ${Q}^{2}$ fit. Also, the ratio $\sqrt{{Q}^{2}}{F}_{{2}_{p}}{/F}_{{1}_{p}}$ reaches a constant value above ${Q}^{2}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2{\mathrm{GeV}}^{2}$.

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.
