Confining Bond Rearrangement in the Random Center Vortex Model

We present static meson-meson and baryon–anti-baryon potentials in Z(2) and Z(3) random center vortex models for the infrared sector of Yang-Mills theory, i.e., hypercubic lattice models of random vortex world-surfaces. In particular, we calculate Polyakov loop correlators of two static mesons resp. (anti-)baryons in a center vortex background and observe that their expectation values follow the minimal area law and show bond rearrangement behavior. The static meson-meson and baryon–anti-baryon potentials are compared with theoretical predictions and lattice QCD simulations.
