Rigorous inequalities on the derivatives ofS- andP-wave amplitudes for π-π scattering

Строгие неравенства на ПроиэводныеS иP Парциальных амПлитуд для π-π рассеяния

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

Summary

Inequalities involving theS- andP-wave pion-pion amplitudes and their first derivatives are obtained from crossing symmetry and positivity properties for some isospin combinations. They can be used to test low-energy models.

Riassunto

Dalla simmetria incrociata e dalle proprietà di positività per alcune combinazioni di isospin si ricavano le disuguaglianze interessanti le ampiezze pione-pione d’ondaS eP e le loro derivate prime. Si possono sfruttare i risultati ottenuti per verificare i modelli di bassa energia.

Реэюме

Иэ кроссинг-симметрии и свойств Положительности для некоторых иэосПиновых комбинаций Получаются неравенства, включаюшиеS иP Парциальные Пион-Пионные амПлитуды и их Первые Проиэводные. Эти неравенства могут быть исПольэованы для Проверки моделей для ниэких Энергий.
