Description
Lattice QCD indicates a large amount of entropy associated with the heavy quark-antiquark pair
immersed in the quark-gluon plasma. We argue that the increase of this entropy as a function of the inter-quark distance gives rise to an entropic force that can be very effective in dissociating the bound quarkonium states. In addition, the lattice data show a very sharp peak in the heavy quark-antiquark entropy at the deconfinement transition. In the holographic approach, this peak arises because the heavy quark pair acts as an eyewitness to the black hole formation in the bulk – the process that describes the deconfinement transition. In terms of the boundary theory, this entropy likely emerges from the entanglement of a “long string” connecting the quark and antiquark with the rest of the system.
