Description
In this talk, we present a lattice determination of the coupling constant $\alpha_s$ in $N_f=3$ QCD for renormalization scales $\mu\in(1,2)$ GeV.
The computation has been performed on ensembles generated by the Coordinated Lattice Simulations (CLS) consortium, with tree-level Symanzik-improved gauge action and Wilson O(a)-improved fermions. Our approach is based on the study of current-current correlation functions in position space and allows to determine $\alpha_s$ (or alternatively the $\Lambda$ parameter) with a competitive precision.
