相对论多体反应系统混沌分析的C#程序
Code C# for chaos analysis of relativistic many-body systems with reactions
摘要:
在这项工作中,我们提出了一个反应模块的“混沌多体引擎”(Grossu等人,2010 [1])。按照我们创建一个可定制的、面向对象的代码库的目标,所有可能的反应的列表,包括相应的属性(粒子类型、概率、截面、粒子寿命等),可以使用特定的XML输入文件作为参数提供。受Poincare截面的启发,我们还提出了一种新的多体系统的直观分析方法--“非线性映射”。为了举例说明,我们实现了4.5 A GeV/c核相对论碰撞的数值玩具模型(SKM 200合作)。得到了动量、能量、快度和角π分布与实验数据的令人鼓舞的一致性。
英文摘要:
In this work we present a reactions module for "Chaos Many-Body Engine" (Grossu et al., 2010 [1]). Following our goal of creating a customizable, object oriented code library, the list of all possible reactions, including the corresponding properties (particle types, probability, cross-section, particles lifetime etc.), could be supplied as parameter, using a specific XML input file. Inspired by the Poincare section, we propose also the "Clusterization map", as a new intuitive analysis method of many-body systems. For exemplification, we implemented a numerical toy-model for nuclear relativistic collisions at 4.5 A GeV/c (the SKM200 collaboration). An encouraging agreement with experimental data was obtained for momentum, energy, rapidity, and angular π- distributions.
