QCD static force in gradient flow
We review our recent study on the QCD static force using gradient flow at next-to-leading order in the strong coupling. The QCD static force has the advantage of being free of the O(ΛQCD) renormalon appearing in the static potential but suffers from poor convergence in the lattice QCD computations....

| description | We review our recent study on the QCD static force using gradient flow at next-to-leading order in the strong coupling. The QCD static force has the advantage of being free of the O(ΛQCD) renormalon appearing in the static potential but suffers from poor convergence in the lattice QCD computations. It is expected that the gradient flow formalism can improve the convergence. Based on our next-to-leading-order calculations, we explore the properties of the static force for arbitrary flow time t, as well as in the limit t → 0, which may be useful for lattice QCD simulations. |
