Summary
The formalism of Delbourgo, Salam and Strathdee is extended to inelastic backward scattering and it is shown that the absence of dip in the backward photoproduction of pions follows as a natural consequence ofO 3,1 symmetry of scattering amplitudes.
Riassunto
Si estende il formalismo di Delbourgo, Salam e Strathdee allo scattering anelastico all’indietro e si mostra che l’assenza di pendenza nella fotoproduzione all’indietro di pioni segue come una conseguenza naturale della simmetriaO 3,1 delle ampiezze di scattering.
Реэюме
Формалиэм Дельбурго, Салама и Стратди обобшается на неупругое рассеяние в направлении наэад. Покаэывается, что отсутствие понижения в фоторождении пионов в направлении наэад является естественным следствиемO 3, 1 симметрии амплитуд рассеяния.
