MathQCDSR: A Mathematica package for QCD sum rules calculations
收藏资源简介：
Abstract We present a software package written in Mathematica for standard QCD sum rules calculations. Two examples are given to demonstrate how to use the package. One is for the mass spectrum of octet baryons from two-point correlation functions; the other for the magnetic moments of octet baryons in the external-field method. The free package FeynCalc is used to handle the gamma-matrix algebra. In addition to two notebooks for the construction of the QCD sum rules, two corresponding notebooks are p... Title of program: MathQCDSR Catalogue Id: AEJA_v1_0 Nature of problem The QCD sum rule method is a nonperturbative approach to solving quantum chromodynamics (QCD), the fundamental theory of the strong force. The approach establishes a direct link between hadron phenomenology and the QCD vacuum structure via a few QCD parameters called vacuum condensates and susceptibilities. It has been widely applied in nuclear and particle physics to gain insight into various aspects of strong-interaction physics. Versions of this program held in the CPC repository in Mendeley Data AEJA_v1_0; MathQCDSR; 10.1016/j.cpc.2011.04.017 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
摘要 本文介绍一款基于Mathematica编写的标准量子色动力学（Quantum Chromodynamics，QCD）求和规则计算软件包。文中给出两个示例以演示该软件包的使用方法：其一为基于两点关联函数的八重态重子质量谱计算；其二为利用外场方法求解八重态重子的磁矩。本软件包借助免费开源软件包FeynCalc处理γ矩阵代数运算。除了两份用于构建QCD求和规则的Mathematica笔记本文件外，另有两份对应的笔记本文件（原文此处未完整呈现）。 程序名称：MathQCDSR 目录编号：AEJA_v1_0 问题属性： QCD求和规则方法是求解强相互作用基本理论量子色动力学（QCD）的非微扰途径。该方法通过少量被称为真空凝聚与磁化率的QCD参数，建立了强子唯象学与QCD真空结构之间的直接联系，已广泛应用于核物理与粒子物理领域，以深入探究强相互作用物理的诸多方面。 Mendeley数据的CPC仓库中收录的该程序版本为：AEJA_v1_0；MathQCDSR；DOI:10.1016/j.cpc.2011.04.017。本程序源自贝尔法斯特女王大学托管的CPC程序库（1969-2018）。
