Pseudopotential of Hybrid Mesons in a Holographic Anisotropic Plasma

Abstract We study the pseudopotential of hybrid mesons in a holographic anisotropic background using the AdS/CFT correspondence. The hybrid states are introduced by incorporating a defect, whose force balance condition is analyzed within the string configuration. From this, we derive the balance equation and compute key physical quantities, including the separation distance, pseudopotential, and binding energy of the hybrid mesons. It is found that increasing the anisotropy parameter $a$ leads to a decrease in the separation distance for both the ground and excited states. However, while the ground-state potential decreases, the pseudopotential of the hybrid state increases. Additionally, we find that the pseudopotential of the hybrid mesons exhibits significant sensitivity to changes in the angular parameter $\alpha$
