Abstract
We consider a heavy quark-antiquark (qq¯) pair as a heavy meson in the medium composed of light quarks and gluons. By using the AdS/CFT correspondence, the properties of this system are investigated. In particular, we study the inter-quark distance and it is shown that the mechanism of melting in the quark-gluon plasma and in the hadronic phase is the same. It is found that by considering finite-coupling corrections, the inter-quark distance of a heavy meson decreases. As a result a heavy meson like J/Ï will melt at higher temperatures. By considering rotating heavy mesons, we discuss melting of exited states like Ïc and Ïâ².
