Abstract
We present SU(3) lattice gauge theory results for the O(1/mQ) hybrid spin-dependent and hybrid-quarkonium mixing potentials. The only existing lattice computation of these potentials is limited to quark-antiquark separations smaller than approximately 0.5\,fm. In this work, we extend the lattice results up to around 1.25 \, fm using large-volume, high-statistics simulations at several lattice spacings and gradient flow times, providing the first lattice data in this previously unexplored regime.
