Abstract

We present the initial release of ARGES, a toolkit for obtaining renormalisation group equations in perturbation theory. As such, ARGES can handle any perturbatively renormalisable four-dimensional quantum field theory. Notable further features include a symbolic rather than numeric computation, input of unconventional scalar and Yukawa sectors, an interactive evaluation and disentanglement as well as capabilities to inject algebraic simplification rules. We provide a conceptual and practical introduction into ARGES, and highlight similarities and differences with complementary packages. Program summary:

Program Title: ARGES
CPC Library link to program files: https://doi.org/10.17632/s2vhxgsk7s.1
Licensing provisions: GPLv3
Programming language: Wolfram Language (Mathematica)
Nature of problem: Computation of renormalisation group equations of perturbatively renormalisable quantum field theories in four space-time dimensions to various orders in the loop expansion.
Solution method: Automatize computation of RGEs from input of field content, representations, couplings and index contractions.
Additional comments including restrictions and unusual features: Allows for variable generations, symmetry representations, and gauge groups. Advanced algebraic structures can be defined via simplification rules.
