Summary
The independent source model for hadron-nucleus collisions is generalized to include nucleus-nucleus collisions. A simple analytical formula for transverse energy distributions is derived which is then compared with the recent experimental data obtained by NA35 Collaboration at CERN SPS. The features of the experimental results are shown to be the natural consequences of the generalized model.
Riassunto
Si generalizza il modello indipendente della sorgente per le collisioni adrone-nucleo per includere le collisioni nucleo-nucleo. Si deduce una semplice formula analitica per le distribuzioni di energia transversali che è poi confrontata con i dati sperimentali recenti ottenuti dalla Collaborazione NA35 al SPS del CERN. Si mostra che le caratteristiche dei fatti sperimentali sono le naturali conseguenze del modello generalizzato.
Реэюме
Предлагается обобшние модели неэависимых источников для соударений адронов с ядрами, чтобы описать соударения ядер с ядрами. Выводится простая аналитическая формула для распределений поперечных знергий, которая эатем сравнивается с недавними зкспериментальными данными, полученными NA35 коллаборацией в ЦEPHe на SPS. Покаэывается, что характерные особенности зкспериментальных данных следуют иэ обобшенной модели.
