rg beta function RGBeta is a Mathematica package that allows the user to extract RG beta-functions up to loop order 4-3-3 for gauge, Yukawa, and quartic couplings, respectively, for a large class of 4D renormalizable models. If you use RGBeta, please cite arXiv:2101.08265..

vao bong88 org  In a sense the definition of RG is ambiguous since the beta-functions of the couplings depend implicitly on Z(μ)? Another more concrete way to phrase this question is why did we choose the wavefunction renormalization in order to keep the kinetic term intact after RG flow?

rg betim  In completely generic four-dimensional gauge-Yukawa theories, the renormalization group $ β$-functions are known to the 3-2-2 loop order in gauge, Yukawa, and quartic couplings, respectively. It does, however, remain difficult to apply these results to specific models without the use of dedicated computer tools. We describe a procedure for extracting $ β$-functions using the general results ...
