Relativistic corrections to the static potential at O(1/m) and O(1/m2)

Abstract

We investigate the relativistic corrections to the static potential, the O(1/m) potential and the O(1/m2) velocity-dependent potentials, in SU(3) lattice gauge theory. Utilizing the multi-level algorithm, we obtain remarkably clean signals of these potentials up to r = 0.9 fm. We observe long range nonperturbative contributions to these corrections.
