Dispersion-theoretical calculation of Coulomb corrections to the π phase shifts

Бычисление кулоновских поправок к сдвигам фаз при π с помошью теории дисперсионных соотношений

Summary

TheS-matrix method of Dashen-Frautschi is used to calculate Coulomb corrections to the π phase shifts. The agreement with the conventional method of van Hove and Schnitzer in the nonrelativistic region is very good. This is another confirmation of theS-matrix method and opens the way to a relativistic treatment of the problem.

Riassunto

Si usa il metodo della matriceS di Dashen e Frautschi per calcolare le correzioni coulombiane agli spostamenti di fase di π. L'accordo con il metodo convenzionale di van Hove e Schnitzer nella regione non relativistica è molto buono. È un'altra verifica della validità del metodo della matriceS e apre la via ad una trattazione relativistica del problema.

Резюме

Для вычисления кулоновских поправок π сдвигу используется методS-матрицы Дашена-Фраутчи. Получается хорошее согласие с общепринятым методом ван Хова и Шнитцера в нерелятивистской области. Это представляет еще одно подтверждение методаS-матрицы и указывает путь для релятивистского рассмотрения проблемы.
