Аннотация:
I will summarize work done obtaining four-loop QCD beta-function in momentum subtraction scheme and three-loop renormalization of bilinear operators used for precise quark mass determination from lattice data.
The status of QCD calculations in the momentum subtraction scheme in the symmetric point is discussed. We explain in detail the evaluation of a new set of three-loop integrals being a necessary part of the presented result.
Talk is based on our recent papers 2002.02875 [hep-ph] and 2002.12758 [hep-ph].
