The Static Potential to O(\alpha^2) in Lattice Perturbation Theory

Abstract

We present a calculation of Wilson loops, and the static inter-quark potential to $O({\alpha }^2)$ in lattice perturbation theory. This is carried out with the Wilson, Symanzik-Weisz, and Iwasaki gauge actions and the Wilson, Sheikholeslami-Wohlert, and Kogut-Susskind dynamical fermion action for small Wilson loops, and with the Wilson gauge action and each of the dynamical quark actions in the case of the static potential.
