Contribution

It introduces a vortex model approach to compute the baryonic potential, demonstrating the Y law's consistency with lattice data for the first time.

Findings

Y law predictions match measured baryonic potentials

String tension anisotropy is carefully considered

Vortex model effectively describes infrared sector of SU(3)

Abstract

The baryonic potential in the framework of the SU(3) random vortex world-surface model is evaluated for a variety of static color source geometries. For comparison, carefully taking into consideration the string tension anisotropy engendered by the hypercubic lattice description, also the Delta and Y law predictions for the baryonic potential are given. Only the Y law predictions are consistent with the baryonic potentials measured.
