Low-energy ππ scattering parameters

Параметры ππ рассеяния при низких энергиях

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

We use the Froissart-Gribov representation and derivatives thereof to calculate scattering lengths and effective-range parameters for the lowest (up to and including ι=4) ππ partial waves. The results are discussed.

Riassunto

Si usano la rappresentazione di Froissart-Gribov e sue derivate per calcolare le lunghezze di scattering e i parametri dell'intervallo effettivo per le onde parziali ππ inferiori (fino a ι=4 compreso). Si discutono i risultati.

Резюме

Мы используем преобразование Фруассара-Грибова и его производные для вычисления длин рассеяния и параметров эффективной области для низших (вплоть до и включая ι=4) парциальных волн для системы ππ. Обсуждаются полученные результаты.
