Description
We measure the static force directly by inserting chromo electric fields into the Wilson loop. We use the gradient flow to improve the signal-to-noise ratio, and to renormalize the field components. Furthermore, we can perform the continuum and zero flow time limit, obtaining a first direct determination of the QCD static force.
By comparing the lattice result with a perturbative calculation of the force, we can aim at a precise extraction of $\Lambda_0$. Additionally, we obtain a determination of the scales $r_1$, and $r_0$.
