Summary
Violations of the quark line (IOZ) rule in production quasi—two-body reactions are reviewed. It is argued that there is an experimental support for a systematic excess of IOZ rule violations in production reactions as compared with decay processes. The significance of this result is discussed within the domains of the dual unitarization model and a detailed numerical study of π−p → ϕn is presented.
Riassunto
Si rivedono le violazioni della regola di IOZ della linea di quark nella produzione di reazioni quasi a due corpi. Si arguisce che c’è una conferma sperimentale dell’eccesso sistematico delle violazioni della regola IOZ nelle reazioni di produzione in confronto ai processi di decadimento. Il significato di questo risultato è discusso all’interno del dominio del modello di unitarizzazione duale e si presenta uno studio numerico dettagliato della reazione π−p→φn.
Реэюме
Аналиэируются нарущения правила для кварковых линий в реакциях с обраэованием двух кваэичастиц. Покаэывается, что сушествует зкспериментальное подтверждение для систематических нарущений правила для кварковых линий в реакциях рождения по сравнению с процессами распада. Обсуждается эначимость зтого реэультата в областях дуальной унитариэованной модели. Проводится подробное численное исследование процесса 7т~р → фп.
