Peculiar features of the relations between pole and running heavy quark masses and estimates of the O(\alpha_s^4) contributions

Kataev, A. L., Kim, V. T.

Understand

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 $\pi^2$-effects, which exist in the coefficients of these series.
  • The estimates of order $O(\alpha_s^4)$ QCD corrections are presented.
