论文摘要
本研究基于由340-GEV负亲与乳液核引起的相互作用。本文的主要目的是研究中央碰撞事件的某些方面。因此,选择了带电淋浴颗粒总数大于或等于28(NS GEQ 28)的事件进行分析。它们不是完全的中心碰撞事件,但可以被视为伪中央碰撞事件。已经研究了相对论中心的次生的角度特征,从伪长度上进行了研究,在分布中发现双峰性不存在。平均伪宽度似乎与灰色和重粒子多样性无关,这表明其与碰撞数的独立性。最后,讨论了本文中不同粒子多样性之间的相关性。
The present study is based on the interactions caused by 340-GeV negative pions with emulsion nuclei. The main aim of this paper is to investigate some aspects of central collision events. Thus, the events in which the total number of charged shower particles is greater than or equal to twenty eight (Ns geq 28) were chosen for the analysis. They are not exactly central collision events, but may be considered as pseudo-central collision events. The angular characteristics of relativistic charged secondaries have been studied in terms of pseudo-rapidity, and bimodality is found to be absent in the distributions. The mean pseudo-rapidity seems to be independent of grey and heavy particle multiplicities, which indicates its independence with number of collisions. Finally, the correlation between different particle multiplicities in this paper is discussed.
