Summary
We investigate backward pion photoproduction with the Regge-pole model, including kinematic cuts to remove parity doublets. A satisfactory fit of the data is obtained, but no unique set of parameters can be found by the available differential cross-section data.
Riassunto
Si esamina la fotoproduzione di pioni all’indietro con il modello dei poli di Regge, includendo tagli cinematici per eliminare i doppietti di parità. Si ottiene un buon accordo con i dati, ma, in base ai dati disponibili sulle sezioni d’urto differenziali, non si è potuto trovare un gruppo di parametri unico.
Реэюме
Мы исследуем фоторождение пионов в направлении наэад, испольэуя модель полюсов Редже, которая включает кинематические реэреэы для устранения дублетов по четности. Получается удовлетворительное согласие с зкспериментальными данными, но не может быть найдена единственная система параметров, испольэуя опубликованные данные по дифференциальным поперечным сечениям.
