Abstract

fetched live from OpenAlex

Inclusive measurements of the pion differential cross sections and analyzing powers have been made for the reaction $pp\\to pn\\pi\\sp+$ over the angular range 24$\\sp\\circ$ to 100$\\sp\\circ,$ using the SASP spectrometer at TRIUMF. A 1 cm thick liquid hydrogen target was used, with an identical empty cell for background determination. These studies included the $pp\\to d\\pi\\sp+$ reaction for verification of the cross section normalization. Measurements extended to pion momenta as low as 80 MeV/c. Experimental cross sections are compared with a final state interaction model prediction and the contribution of the $\\sigma\\sb{11}$ term. The analyzing powers closely follow those of the $pp\\to d\\pi\\sp+$ reaction at the same centre of mass momentum and energy.

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.
