Parity Violation in Proton-Proton Scattering at 221 MeV
Bibliographic record
Abstract
The parity-violating longitudinal analyzing power, ${A}_{z}$, has been measured in $\stackrel{\ensuremath{\rightarrow}}{p}p$ elastic scattering at an incident proton energy of 221 MeV. The result obtained is ${A}_{z}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}[0.84\ifmmode\pm\else\textpm\fi{}0.29(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.17(\mathrm{syst})]\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}7}$. This experiment is unique in that it selects a single parity violating transition amplitude ${(}^{3}{P}_{2}^{1}\ensuremath{-}D_{2})$ and consequently directly constrains the weak meson-nucleon coupling constant ${h}_{\ensuremath{\rho}}^{\mathrm{pp}}$. When this result is taken together with the existing $\stackrel{\ensuremath{\rightarrow}}{p}p$ parity violation data, the weak meson-nucleon coupling constants ${h}_{\ensuremath{\rho}}^{\mathrm{pp}}$ and ${h}_{\ensuremath{\omega}}^{\mathrm{pp}}$ can, for the first time, both be determined.

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; a candidate call from one teacher head, not a consensus.
