Peculiar features of the relations between pole and running heavy quark masses and estimates of the O(αs4) contributions

Perturbative relations between pole and running heavy quark masses, defined in the Minkowski regions, are considered. Special attention is paid to the appearance of the kinematic π 2 -effects, which exist in the coefficients of these series. The estimates of order O ( α s 4 ) QCD corrections are pre...

Summary:Perturbative relations between pole and running heavy quark masses, defined in the Minkowski regions, are considered. Special attention is paid to the appearance of the kinematic π 2 -effects, which exist in the coefficients of these series. The estimates of order O ( α s 4 ) QCD corrections are presented.
