Abstract

fetched live from OpenAlex

Recent analyses are reviewed that determine the amplitude structure of meson baryon scattering directly from the data.Harari's explanation of the "crossover" effect in elastic scattering is introduced, motivating the evaluation of a0 and f" exchange amplitudes from the data.Uncertainties in the analysis of the f" amplitude are detailed, and are noted to arise from the uncertainty in the pomeron contribution to elastic scattering.Finally, the dual absorptive model (DAM) of Harari is presented and compared to data on charge exchange and strangeness exchange reactions.Particular emphasis is placed on the comparison of the DAM to the crossed reactions 7(p -+K(A,C) and !?p -+fl(A,~).

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
