Abstract
The proton, at one time, was thought to be a fundamental particle. It's of course now recognized that it and its fellow hadrons are composed of quarks. This composition gives rise to parameters, called polarizabilities, that describe how this structure responds to external electric and magnetic fields. To study these polarizabilities, a Compton scattering program has been ongoing in the A2 experimental hall at the Mainz Microtron. There, a tagged Bremsstrahlung beam of either linearly or circularly polarized photons is scattered off of either unpolarized protons in a liquid hydrogen target, or polarized protons with spins transverse or longitudinal to the beam direction. Different combinations allow for the measurement of different polarization observables, using the nearly 4$\pi$ steradian coverage provided by the combination of the Crystal Ball and TAPS detectors. Combined fits of these parameters then permit an extraction of these polarizabilities, some of which had not previously been experimentally determined. These proceedings will discuss the status and outlook of the A2 Compton program.

How this classification was reachedexpand
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.
