- Аннотация: We briefly review how it is possible to derive some exact expressions for the renormalization constants for the MS-like renormalization prescriptions using the arguments based on the renormalization group. These expressions are obtained for a version ofthe dimensional technique in which the dimensionful parameter Λ differs from the renormalizationscale μ. They encode the equations relating the coefficients at higher ε-poles, powers of ln Λ/μ, and mixed terms of the structure ε−q lnp Λ/μ to the coefficients of the renormalization group functions (i.e. of the β-function and the anomalous dimension). The general results are verified by some multiloop calculations.
