Quark binding potential and QGP

The effect of quark-antiquark potential on the dissociation energy and critical screening length of heavy meson like $b\overline{b}$ and $c\overline{c}$ have been investigated when the respective meson is in quark Gluon Plasma(QGP). The different types of interquark potential have been used which get screened in the QGP medium. The dissociation energy and critical screening length have been studied for both ground and excited states. It has been observed that the form of interquark potential has substantial effect on the critical screening length when the meson is in QGP. A comparison with other theoretical studies are made.
