The matching condition which determines the effect of a heavy quark threshold on the running of the QCD coupling $\alpha_{\overline{MS}}$ is reviewed. The matching scale is arbitrary to some extent. However, this affects the value of $\alpha_{\overline{MS}}$ away from the threshold region only marginally.

  1. Smooth Threshold Effects from Dimensional Regularization

    hep-th 2026-04 unverdicted novelty 4.0

    A mass-dependent renormalization scheme from dimensional regularization yields smooth threshold transitions in QCD and implements the Appelquist-Carazzone theorem by reducing to minimal subtraction at high energies.
