Multiplicity distribution formula for the range (10÷405) GeV/c and extension to a joint distribution

Формула для распределения множественности в области (10÷405)ГзB/c и распространение на случай совместного распределения

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

A multiplicity distribution formula in terms of the cumulants of the distribution is studied for charged-particle production in pp and π±p reactions in the range (10÷405) GeV/c and also for the multiplicity distribution of events with Λ, K 0 S , K+Λ, (K0 \(K\) 0) c=+1 and K0Λ inclusive production in the pp reaction at 19 GeV/c. Its implication for KNO scaling is discussed. In the appendix a formula is derived for the semi-inclusive probability distribution of two distinct kinds of particles.

Riassunto

Si studia una formula di distribuzione della molteplicità in termini dei cumulanti della distribuzione per la produzione di particelle cariche nelle reazioni pp e π±p nel campo di (10÷405) GeV/c ed anche per la distribuzione della molteplicità di eventi con la produzione inclusiva di Λ, K 0 S , K+Λ, (K0 \(K\) 0) c=+1 e K0Λ nella reazione pp a 19 GeV/c Si discute la sua implicazione sulle variazioni di scala di KNO. Nell’appendice si deduce una formula per la distribuzione della probabilità semiinclusiva di due tipi distinti di particelle.

Реэюме

Исследуется формула для распределения множественности в терминах « кумулянтов » распределения для рождения эаряженных частиц в рр и π±p реакциях в области (10÷405) ГзB/c, а также для распределения множественности для событий инклюэивного рождения Λ, K 0 s , K+Λ, (K0 \(K\) 0) c=+1 и K0Λ в рр реакции при 19 ГзB/c. Обсуждается применение полученных реэультатов к KNO скейлингу. В Приложении выводится формула для полуинклюэивного вероятностного распределения для двух раэличных типов частиц.
