rg beta function The RG flow of the coupling constant hα is given by the beta-function in this context is defined as which ≡ α − ln b (15.19) which measures the rate of change (heff (b) of the coupling hα for a logarithmic change in the UV scale, ln b = ln(a′/a). For b → 1, the beta-function reduces to ∂hα = =.

link 1xbet aviator 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?
