Summary
We propose a few general empirical laws summarizing our knowledge on two-body hadronic amplitudes. These systematics lead to a simple analytic parametrization of these amplitudes, allowing the reproduction of all the prominent features of the nonvacuum exchange data from 6 to 50 GeV/c. The obtained results, and in particular the ability of describing in a consistent way both meson and baryon exchanges, are encouraging and suggest that a framework may be found for new dynamical approaches.
Реджеометрия
Резюме
Мы предлагаем несколько обших эмпирических законов, которые суммируют наши знания о двухчастичных адронных амплитудах. Предложенная систематика приводит к простой аналитической параметризации этих амплитуд, что позволяет воспроизвести все сушественные особенности экспериметальных данных в области от 6 до 50 Г эВ/с. Полученные результаты и, в частности, возможность описания непротиворечивым образом мезонных и барионных обменов являются обнадеживающими и дают возможность предположить, что может быть найдена основа для новых динамических подходов.
Riassunto
Si propongono poche regole generali empiriche che riassumono le nostre conoscenze sulle ampiezze adroniche di due corpi. Questa sistematica porta a una semplice parametrizzazione analitica di queste ampiezze, permettendo di riprodurre tutti gli aspetti preminenti dei dati di scambio nel non vuoto da 6 a 50 GeV/c. I risultati ottenuti, e in particolare la capacità di descrivere in maniera consistente gli scambi sia di mesoni che di barioni, sono incorragianti e suggeriscono che si può trovare un inquadramento per nuovi approcci dinamici.
