Abstract

We compute hybrid static potentials in SU(3)SU(3) lattice Yang-Mills theory at short quark-antiquark separations using four different small lattice spacings as small as 0.04fm0.04\,\text{fm}. The resulting static potentials are important, e.g. when studying heavy hybrid mesons in the Born-Oppenheimer approximation. We also discuss and exclude possible systematic errors from topological freezing, the finite lattice volume and glueball decays.
