SU(3) hybrid static potentials at small quark-antiquark separations from fine lattices

Abstract

We summarize our recent lattice gauge theory computation of the ${\Pi }_u$ and ${\Sigma }_u^{-}$ hybrid static potentials at small quark-antiquark separations. We provide parameterizations of the resulting lattice data points, which can be used for investigating masses and properties of heavy hybrid mesons in the Born-Oppenheimer approximation.
