Summary
We discuss the currently accepted model used to describe the reaction π + d → p + p. We show that this model is inconsistent with unitarity constraints and with our general understanding of pion-deuteron interactions. An alternate calculational procedure is proposed.
Riassunto
Si discute il modello correntemente accettato per descrivere la reazione π + d → p + p. Si mostra che questo modello non è consistente con i vincoli di unitarietà e con la nostra generale comprensione delle interazioni pione-deuterone. Si propone un procedimento di calcolo alternativo.
Реэюме
Мы обсуждаем принятую в настояшее время модель для описания реакции π + d → p + p. Мы покаэываем, что зта модель согласуется с ограничениями унитарности и с интерпретацией вэаимодействий пиона с дейтроном. Предлагается альтернативная процедура вычисления.
