Description
rg beta function Renormalization Group Equations (RGEs) are indispensable tool to know the behavior of physical parameters at different energy scales. They are also extremely crucial if we want to extend our known Standard Model gauge group by some extra gauge groups and the $β$-functions are the soul of these RGEs. In literature although it is quite common to find long, final expressions of the RGEs ....
rg beton 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?
