Exotic Hybrid Quark Potentials [PDF]
Oleg AndreevWe use gauge/string duality to model some hybrid heavy-quark potentials. The potentials under consideration can't be described by a single Nambu-Goto string. This is why we call them "exotic". For $\Sigma_u^-$, the result is in quite good agreement with lattice simulations.View original: http://arxiv.org/abs/1207.1892
