Анализ обобщенного распределения множественностн в различных диапазонах псевдобыстроты

Il Nuovo Cimento A (1965-1970)

Summary

It is found that the data on multiplicity distributions of charged particles at various pseudorapidity ranges for inelastic, non single-diffractive events in\(p\bar p\) interactions at\(\sqrt {s = 540} \) GeV, can be well described by a generalized multiplicity distribution. The parameterk′ (average number of initial gluons) in the generalized multiplicity distribution appears to be close to zero wheres, 1.58≤k≤3.10 (k, related to the average number of initial quarks) at the different pseudorapidity ranges.

Riassunto

Si trova che i dati sulle distributioni di molteplicità di particelle cariche a vari intervalli di pseudorapidità per eventi anelastici, non singoli diffrattivi nelle interazioni\(p\bar p\) a\(\sqrt {s = 540} \) GeV possono essere ben descritti da una distribuzione di molteplicità generalizzata. Sembra che il parametrok′ (numero medio di gluoni iniziali) nella distribuzione di molteplicità generalizzata sia vicino a zero mentre 1.58≤k≤3.10 (k, connesso al numero medio di quark iniziali) ai diversi intervalli di pseudorapidità.

Резюме

Показывается, что данные для распределений множественности заряженных частиц, образованных в\(p\bar p\) взаимодействиях при\(\sqrt {s = 540} \) МэВ, могут быть хорошо описаны с помощью обобщенного распределения множественности. Параметрk′ (среднее число начальных глюонов) в обобщенном распределении множественности окзывается близким к нулю, тогда как 1.58≤k≤3.10 (где параметрk связан со средним числом начальных кварков) в различных диапазонах псевдобыстроты.
