Hybrid meson pseudopotentials from a holographic model with gluon condensation

Abstract

Utilizing the holographic gauge/gravity duality, we investigate the behavior of hybrid mesons in the presence of gluon condensation. By incorporating a localized defect into a dilaton-gravity background to simulate gluonic excitations, we study the interquark distance and the associated pseudopotential. The results show that the hybrid pseudopotential follows a quadratic behavior that intensifies with the gluon condensate. Furthermore, the reduction in screening length indicates that increased condensation promotes the dissociation of these exotic states.
