On Exotic Hybrid Pseudo-Potentials and Gauge/String Duality

Abstract

We use gauge/string duality to model some hybrid pseudo-potentials in a pure SU(N) gauge theory. The pseudo-potentials under consideration can't be described by a single Nambu-Goto string. This is why we call them "exotic". A comparison with the calculation of the pseudo-potential shows the universality of the spatial string tension.
