On the relation between pole and running heavy quark masses beyond the four-loop approximation
... Let us now apply the used in [? ] approach for estimations of the high-order PT QCD correc- tions to the relation between di ff erent definitions of heavy quarks. This approach is following the lines of the developed in ...
