Slow running of the Gradient Flow coupling from 200 MeV to 4 GeV in $N_{\rm f}=3$ QCD
Using a finite volume gradient flow renormalization scheme with Schrödinger Functional boundary conditions, we compute the nonperturbative running coupling in the range 2.2≲g¯GF2(L)≲13. Careful continuum extrapolations turn out to be crucial to reach our high accuracy. The running of the coupling is...
