摘要

AbstractFractals, random, and AMPT AuAu events are analyzed using \(SePaC\) method.在五个中心性类别中考察了带负电粒子的横向矩\({{p}_{text{t}}}}\ )。结果表明，具有独立分区的分形 AuAu 事件在分形维数 \({{D}_{text/{F}}}}\)谱中具有几个狭窄的峰值，并且所有事件的横向动量 \({{p}_{text/{t}}}}\)中都有一组分离的领先粒子，并且满足描述统计特性的标准。其余的事件则表现出 \({{p}_{text{t}}}}\)谱的指数行为。具有依赖分区的分形金金事件在 \({{D}_{text{F}}}}\) 谱中有一个宽峰，并被选择标准所抑制。

Search for Fractal Structures in Monte Carlo AuAu Events at an Energy of 200 GeV by the SePaC Method

Abstract

Fractals, random, and AMPT AuAu events are analyzed using the \(SePaC\) method. Transverse momenta \({{p}_{{\text{t}}}}\) of negatively charged particles are examined in five centrality classes. Fractal AuAu events with independent partition are shown to feature several narrow peaks in the spectrum of fractal dimensions \({{D}_{{\text{F}}}}\) and a separated group of leading particles in transverse momentum \({{p}_{{\text{t}}}}\) for all events and to satisfy the criteria that describe statistical properties. Remaining events exhibit exponential behavior of the \({{p}_{{\text{t}}}}\) spectrum. Fractal AuAu events with dependent partition have a broad peak in the \({{D}_{{\text{F}}}}\) spectrum and are suppressed by selection criteria.

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
