Quarkonium Binding and Entropic Force

Understand

A Q-Qbar bound state represents a balance between repulsive kinetic and attractive potential energy.

• In a hot quark-gluon plasma, the interaction potential experiences medium effects.
• Color screening modifies the attractive binding force between the quarks, while the increase of entropy with Q-Qbar separation gives rise to a growing repulsion.
• We study the role of these phenomena for in-medium Q-Qbar binding and dissociation.
