Summary

A Regge-type amplitude for πN charge exchange scattering is used as an input in anN/D partial-wave analysis. By taking into account only the ρ trajectory and unitarity, poles of various partial waves (l=0 to 5) are found. We compare our results with the experimental data and with the Argand diagram analysis results.

Riassunto

Un'ampiezza del tipo di Regge per lo scattering con scambio di carica πN si usa come entrata in un'analisi in onde parzialiN/D. Considerando solo la traiettoria del ρ e l'unitarietà, si trovano poli di diverse onde parziali (l=da 0 a 5). Si confrontano questi risultati con i dati sperimentali e con i risultati dell'analisi dei diagrammi di Argand.

Резюме

Используется амплитуда реджеева типа для πN рассеяния с перезарядкой, как основа дляN/D анализа по парциальным волнам. Учитывая только ρ траекторию и унитарность, получаются полюса для различных парциальных волн (l=от 0 до 5). Мы сравниваем наши результаты с экспериментальмыми данными и с результатами анализа диаграмм Арганда.
