Absolute bound on the ππ scattering amplitude

Абсолютная граница для ππ амплитуды рассеяния

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

Summary

Combining unitarity with the well-known properties of the Herglotz functions an essential improvement on the upper bound of |F(2, 2, 0)| is obtained under the additional assumptionF(4, 2,−2)<0.

Riassunto

Combinando l'unitarietà con le ben note proprietà delle funzioni di Herglotz si ottiene un miglioramento essenziale del limite superiore di |F(2, 2, 0)| con l'ipotesi aggiuntiva cheF(4, 2,−2)<0.

Резюме

Обьединяя унитарность с хорощо известными свойствами функций Герглотца, получается существенное улучшение верхней границы |F(2, 2, 0)| при дополнительном предположенииF(4,2,−2)<0.
