Abstract
For lattice QCD with two sea quark flavors we study the static quark-antiquark potential in the regime where string breaking is expected. In order to increase the statistics, we make full use of the lattice information by including all lattice vectors to any given separation in the infrared regime. The corresponding paths between the lattice points are constructed by means of a generalized Bresenham algorithm as known from computer graphics. As a result, we achieve a determination of the Wilson loops in the range with hitherto unknown precision. Finally, we discuss the impact of this approach on the signal of the transition matrix element between two- and four-quark states.
