On Melting Temperature of Heavy Quarkonium with the AdS/CFT Implied Potential

Abstract

The quarkonium states in a quark-gluon plasma is examined with the potential implied by AdS/CFT duality. Both the vanila AdS-Schwarzschild metric and the one with an infrared cutoff are considered. The calculated dissociation temperatures for $J/\psi$ and ${\rm Y}$ are found to agree with the lattice results within a factor of two.
