Computing $1\mathrm{/}{m}_Q$ and $1\mathrm{/}{m}_Q^2$ corrections to the static potential with lattice gauge theory using gradient flow

We present selected preliminary lattice gauge theory results for $O(1\mathrm{/}{m}_Q)$ and $O(1\mathrm{/}{m}_Q^2)$ corrections to the static potential. These results are based on Wilson loops with two field strength insertions, which we renormalize using gradient flow. We explore tree level improvement to reduce systematic errors in the Wilson loops due to the finite lattice spacing and flow time, in particular at small temporal and spatial separations.
