Using gauge/gravity duality, we studied the exotic hybrid pseudopotentials at finite temperature and chemical potential. The Sigma hybrid meson can be described by a model including an object called "defect'' on a string linking the quark and antiquark. The Sigma(-)(u) hybrid potential at zero temperature and chemical potential was first proposed by Andreev and is perfectly described. In this study, we extended the aforementioned model to finite chemical potential and compared the separate distance and pseudopotentials of Sigma(+)(g) and Sigma u-. Unlike the Sigma(+)(g) ground state, the Sigma...
