Model of the N-Quark Potential in SU(N) Gauge Theory using Gauge-String Duality

Abstract

We use gauge-string duality to model the $N$-quark potential in pure Yang-Mills theories. For $SU(3)$, the result agrees remarkably well with lattice simulations. The model smoothly interpolates between almost the $\Delta$-law at small distances and the Y-law at large distances.
