Abstract:
The renormalization group method is applied to the three-loop effective potential of the massive theory in the scheme in order to obtain the next-next-next-to-leading logarithm resummation. For this, we exploit four-loop parts of the renormalization group functions , , , and , which were already given to five-loop order via the renormalization of the zero-, two-, and four-point one-particle-irreducible Green's functions, to solve evolution equations for the parameters , , , and within the accuracy of the three-loop order.- phi**n model: 4
