Abstract

The assumptions made in the identification of directchannel Reggepole terms with the resonance amplitude are examined The numerator function as well as the denominator are expanded without assuming the smallness of the imaginary part of α It is shown that in the calculation of Im α the assumptions may not always be satisfied The differential crosssections at typical resonances are calculated taking into account the contributions of the parityreflected states and daughtersИсследуются предположения сделанные при идентификации Редже полюсных членов прямого канала с резонансными амплитудами Производится разложение функций числителя и знаменателя без предположения малости мнимой части α Показывается что при вычислении Im α сделанные предположения могут не всегда удовлетворяться Вычисляются дифференциальные поперечные сечения при типичных резонансах принимая во внимание вклады четности отражающие состояния и дочерниеSi esaminano le ipotesi fatte per identificare i termini dei poli di Regge del canale diretto con lampiezza delle risonanze Si sviluppano in serie la funzione del numeratore e quella del denominatore senza fare lipotesi che la parte immaginaria di α sia piccola Si mostra come nel calcolo di Im α queste ipotesi non sempre possono essere soddisfatte Tenendo conto dei contributi degli stati riflessi rispetto alla parità e delle figlie si calcolano le sezioni durto differenziali per le risonanze tipiche
