Running coupling constant from position-space current-current correlation functions in three-flavor lattice QCD

Salvatore Cali, Krzysztof Cichy, Piotr Korcyl +1

In this Letter, we provide a determination of the coupling constant in three-flavor quantum chromodynamics (QCD), ${\alpha }_s^{\overline{\mathrm{MS}}}(\mu )$, for $\overline{\mathrm{MS}}$ re…
