“…The static QCD potential has been determined to high accuracy in quenched lattice studies with Wilson [229,230,231,232,233,234,235,215,236,237,238,146,239,240,147,241,173,166,242,168] as well as various improved lattice actions [243,121,113,118,114] in SU(2) and SU(3) gauge theories. Results for QCD with sea quarks have been obtained in Refs.…”
