Summary
Regge vertices which appear in asymptotic limits of inclusive and exclusive reactions are compared. Some specific models predict their equality, but a general group-theory expansion shows that, in general, these vertices do not have to be equal. Thus decoupling theorems need not hold.
Riassunto
Si confrontano i vertici di Regge che compaiono nei limiti asintotici di reazioni inclusive ed esclusive. Secondo le previsioni di alcuni modelli specifici tali vertici dovrebbero essere uguali; tuttavia uno sviluppo di tipo generale nell'ambito della teoria dei gruppi dimostra che, in generale, essi non devono essere uguali. Così non è necessario che i teoremi di disaccoppiamento siano validi.
Резюме
Сравниваются Редже-вершины, которые появляются в асимптотических пределах для инклюзивных и эксклюзивных реакций. Некоторые специфические модели предсказывают их равенство, но общее разложение теории групп показывает, что в общем случае эти вершины не должны быть равны. Таким образом, теоремы нарушения связи не должны вышолняться.
