Restrictions: The package deals with only standard (SVZ) QCD sum rule calculations.

We employ a Monte Carlo-based procedure to perform the analysis which allows for realistic error estimates. The matching usually involves searching for minimum П‡ 2. The construction involves a large amount of gamma-matrix algebra, Fourier transform, and Borel transform. By numerically matching the two sides over a range in M, the phenomenological parameters can be extracted. On the hadronic level, it leads to a function of phenomenological parameters and the same M. On the quark level, it leads to a function of QCD parameters and the Borel mass parameter M. Solution method: First, QCD sum rules are constructed by evaluating correlation functions from two perspectives. It has been widely applied in nuclear and particle physics to gain insight into various aspects of strong-interaction physics. The approach establishes a direct link between hadron phenomenology and the QCD vacuum structure via a few QCD parameters called vacuum condensates and susceptibilities. Nature of problem: The QCD sum rule method is a nonperturbative approach to solving quantum chromodynamics (QCD), the fundamental theory of the strong force. Here it is used primarily to handle gamma-matrix algebra. It is a freely available Mathematica package for high-energy physics calculations.
