质子-(反)质子和电子-正电子碰撞中部分子复合的多重数分布

Multiplicity distributions in proton-(anti)proton and electron-positron collisions with parton recombination

I. Zborovský

摘要:

本文提出了一种新的描述质子-(反)质子和电子-正电子碰撞中带电粒子多重数分布的唯象方法。观测到的数据特征解释的基础上的随机物理思想的多次生产。除了部分子迁移和吸收的过程,两个和三个赞助人的增量和减量重组被认为是。用四参数广义超几何分布(GHD)描述了不同能量下多重数分布的复杂行为。建议GHD CMS,ALICE和ATLAS合作测量的数据的应用表明,软多部分子重组过程可以显着体现在PP相互作用在非常高的能量的多重性分布的结构。

英文摘要:

A new approach to phenomenological description of the charged particle multiplicity distributions in proton-(anti)proton and electron-positron collisions is presented. The observed features of the data are interpreted on the basis of stochastic-physical ideas of multiple production. Besides the processes of parton immigration and absorption, two and three patron incremental and decremental recombinations are considered. The complex behaviour of the multiplicity distributions at different energies is described by four parametric generalized hypergeometric distribution (GHD). Application of the proposed GHD to data measured by the CMS, ALICE, and ATLAS Collaborations suggests that soft multiparton recombination processes can manifest itself significantly in the structure of multiplicity distribution in pp interactions at very high energies.
