Neutral Pion Electroproduction in the Resonance Region at High $Q^2$
Bibliographic record
Abstract
Jefferson Lab.-Hall C. Measurement of the differential cross sections for neutral pion electroproduction in the process E- P --& gt; E- PI0 P at Q**2 from 6.06 to 7.924 GeV**2. The experiment uses two spectrometers. The HMS and SOS in Hall C with an unpolarized electron beam of around 5.5 GeV hitting at liquid hydrogen target. The data were gathered in the 2003 run period. Data are given for two settings of the SOS (Short Orbital Spectrometer).. The first DSYS error is due to the uncertainty in the normalization. The second is the remainder of the systematic uncertainty. Jefferson Lab.-Hall C.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
