Heavy Quarkonium States with the Holographic Potential

Understand

The quarkonium states in a quark-gluon plasma is examined with the heavy quark potential implied by the holographic principle.

• Both the vanila AdS-Schwarzschild metric and the one with an infrared cutoff are considered.
• The dissociation temperature is calculated by solving the Schr\"o dinger equation of the potential model.
• In the case of the AdS-Schwarzschild metric with a IR cutoff, the dissociation temperatures for $J/\psi$ and $\Upsilon$ with the U-ansatz of the potential are found to agree with the lattice results within a factor of two.
