Describe
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..
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?
