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)
