Summary
We show that, independently of any dynamical assumption, the relativek-body semi-inclusive correlation functionR (k)n will be equal to (−1)k−1((k−1)!/n k−1) if the corresponding inclusive-correlation effect is weak. The 1/n behaviour of NAL data of relative semi-inclusive correlation at 205 GeV/c may, therefore, be seen as an indication that the actual correlation effect of this process is not very strong.
Riassunto
Si mostra che, indipendentemente da qualsiasi ipotesi dinamica, la funzione di correlazione ak corpi semi inclusiva relativaR (k)n sarà uguale a (−1)k−1((k−1)!/n k−1) se il corrispondente effetto di correlazione inclusiva è debole. Il comportamento 1/n dei dati del NAL della relativa correlazione seminclusiva a 205 GeV/c può, perciò, essere considerato come un’indicazione del fatto che l’effetto della correlazione reale di questo processo non è molto forte.
Реэюме
Мы покаэываем, что неэависимо от динамических предположе-ний, функция относительной полуинклюэивной k-частичной корреляции Rn (k)n равна (− 1)k−1 ((k − I)!/nk−1), если соответствуюший инклюэивный корреляционный зффект является слабым. 1/n. поведение NAL данных для относительной полуинклюэивной корреляции при 205 ГзВ/с, повидимому, укаэывает, что действительный зффект корреляции для зтого процесса не является очень сильным.

This conclusion is of course valid only for correlation between negative-negative charge particles. For positive-negative charge particles, the correlation effect seems to be strong, because of a strong deviation of data from the 1/n curve. Furthermore, positive-negative charge correlation data seem to show characteristics of a production of resonances (XVIII International Conference on High-Energy Physics at Tbilisi, USSR, 1976, private communication).
