Exotic hybrid quark potentials
Abstract
We use gauge/string duality to model some hybrid heavy-quark potentials. The potentials under consideration cannot be described by a single Nambu-Goto string. This is why we call them “exotic.” For Σu-, the result is in quite good agreement with lattice simulations.
