As shown recently, one can obtain additional information from the measured charged particle multiplicity distributions, P(N), by investigating the so-called modified combinants, \(C_j\), extracted from them. This information is encoded in the observed specific oscillatory behaviour of \(C_j\), which phenomenologically can be described only by some combinations of compound distributions based on the Binomial Distribution. So far this idea has been checked in pp and \(e^+e^-\) processes (where observed oscillations are spectacularly strong). In this paper we continue observation of multiparticle production from the modified combinants perspective by investigating dependencies of the observed oscillatory patterns on type of colliding particles, their energies and the phase space where they are observed. We also offer some tentative explanation based on different types of compound distributions and stochastic branching processes.

通过改性结合剂生产多颗粒产品

如最近所示,通过研究从它们中提取的所谓的改良组合剂\(C_j \),可以从测量的带电粒子多重性分布PN)中获得其他信息。此信息以观察到的\(C_j \)的特定振荡行为进行编码,在现象学上只能通过基于二项分布的化合物分布的某些组合来描述。到目前为止,这个想法已经在pp\(e ^ + e ^-\)中进行了检验过程(观察到的振荡异常强烈)。在本文中,我们通过研究所观察到的振动模式对碰撞颗粒类型,能量和相空间的依赖关系,从改进的结合剂角度继续观察多颗粒的产生。我们还根据不同类型的化合物分布和随机分支过程提供了一些初步的解释。
