Current algebra and fixedJ-plane singularities

Алгебра токов и фиксированные сингулярности вJ-плоскости

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

Summary

A systematic study of the consequences of Fubini-Dashen-Gell-Mann sum rules for allt-channel helicity amplitudes is given. The necessity of Kronecker deltas in all sense-sense amplitudes atJ=1 is pointed out. The coefficients of these Kronecker deltas are, apart from kinematical factors, the form factors of the target particles.

Riassunto

Si fa uno studio sistematico delle conseguenze delle regole di somma di Fubini-Dashen-Gell-Mann per tutte le ampiezze di elicità del canalet. Si mette in evidenza la necessità dei delta di Kronecker in tutte le ampiezze senso-senso perJ=1. I coefficienti di questi delta di Kronecker sono, a prescindere dai fattori cinematici, i fattori di forma delle particelle bersaglio.

Резюме

Приводится систематическое исследование следствий правил сумм Фубини-Дашена-Гелл-Манна для спиральных амплитуд вt-канале. Отмечается необходимость сингулярностй, типа δ-символа Кронекера, во всех физических амплитудах приJ=1. Коэффициенты этих δ-символов Кронекера являются, не говоря уже о кинематических факторах, форм-факторами частиц мишени.
