摘要：

Using state of the art lattice techniques we investigate the static baryon potential. We employ the multi-hit procedure for the time links and a variational approach to determine the ground state with sufficient accuracy that, for distances up to similar to 1.2 fm, we can distinguish the Y- and Delta- Ansatze for the baryonic Wilson area law. Our analysis shows that the Delta-Ansatz is favoured. This result is also supported by the gauge-invariant nucleon wave function which we measure for the first time.
