The dependence of average particle momenta on the multiplicity

Зависимость средних импульсов частиц от множественности

Summary

We derive the dependence of the average momenta of secondaries in the transverse and longitudinal direction on the multiplicityN. This is done with the aid of the concept of universality which was introduced in previous papers. We find an asymptotic multiplicity scaling law. To make possible a quantitative comparison with experiment at presently available energies we calculate corrections to the asymptotic results. The corrected curves agree rather well with the data.

Riassunto

Si deduce la dipendenza degli impulsi medi dei secondari nella direzione trasversale e longitudinale dalla molteplicitàN. Si è fatto questo con l’aiuto del concetto di universalità che è stato introdotto in precedenti lavori. Si trova una legge asintotica di variazione di scala della molteplicità. Per rendere possibile un confronto quantitativo con gli esperimenti alle energie attualmente disponibili si calcolano correzioni ai risultati asintotici. Le curve corrette concordano piuttosto bene con i dati.

Реэюме

Мы выводим эависимость средних импульсов вторичных частиц в поперечном и продольном направлениях от множественностиN. Предложенный вывод проиэводится с помошью концепции универсальности, которая была введена в предыдуших статьях. Мы находим эакон скейлинга для асимптотической множест-венности. Для проведения количественного сравнения с зкспериментом при име-юшихся в настояшее время знергиях, мы вычисляем поправки к асимптотическим реэультатам. Исправленные кривые довольно хорошо согласуются с зксперимен-тальными данными.
