We present results on the static three- and four-quark potentials in SU(3) and SU(4), respectively, within quenched lattice QCD. We use an analytic multihit procedure for the time links and a variational approach to determine the ground state. The three- and four-quark potentials extracted are consistent with a sum of two-body potentials, possibly with a weak many-body component at larger distances. For quark separations up to ∼ 1.2 fm where the results are most accurate, we find support for the Δ Ansatz for the baryonic area law. © 2002 The American Physical Society.
