Abstract

Multiplicity fluctuations in two separated pseudorapidity intervals are studied in terms of strongly intensive variables. This work presents results obtained in the MC model with quark-gluon strings as objects extended in pseudorapidity space and acting as particle emitting sources. The string interactions are implemented within the discrete model of local string fusion. Strings of fluctuating length in pseudorapidity are considered in order to estimate the non-critical background of fluctuations. The results on the dependence of strongly intensive observables on the width of acceptance windows, on the pseudorapidity separation between them and on the string density qualitatively describe the available data from the NA61/SHINE and ALICE experiments.

前向后多重波动与伪快速相关性的研究

摘要

根据强集变量研究了两个单独的伪快速区间中的多重波动。这项工作介绍了以夸克-胶子串作为在伪快速空间中扩展并充当粒子发射源的对象在MC模型中获得的结果。字符串交互在局部字符串融合的离散模型中实现。为了估计波动的非关键背景，考虑了伪快速波动长度的字符串。根据强强度可观察物对接收窗口的宽度，它们之间的假快速间隔以及字符串密度的依赖的结果，定性地描述了来自NA61 / SHINE和ALICE实验的可用数据。
