$$J/\Psi $$ suppression in a rotating magnetized holographic QGP matter

Abstract

AbstractWe study the dissociation effect of $$J/\Psi $$ J / Ψ in magnetized, rotating QGP matter at finite temperature and chemical potential using gauge/gravity duality. By incorporating angular velocity into the holographic magnetic catalysis model, we analyze the influence of temperature, chemical potential, magnetic field, and angular velocity on the properties of $$J/\Psi $$ J / Ψ meson. The results reveal that temperature, chemical potential, and rotation enhance the dissociation effect and increase the effective mass in the QGP phase. However, the magnetic field suppresses dissociation, and its effect on the effective mass is non-trivial. Additionally, we explore the interplay between magnetic field and rotation, identifying a critical angular velocity that determines the dominant effect. As a parallel study, we also examine the rotation effect in the holographic inverse magnetic catalysis model, although the magnetic field exhibits distinctly different behaviors in these two models, the impact of rotation on the dissociation effect of $$J/\Psi $$ J / Ψ is similar. Finally, we investigate the influence of electric field and demonstrate that it also speeds up the $$J/\Psi $$ J / Ψ dissociation.
