Heavy Q ‾ Q free energy from hadronic states
Abstract
Within the spirit of the Hadron Resonance Gas model, we study a representation of the heavy Q ‾ Q free energy at temperatures below the phase transition in terms of the string and heavy-light hadrons. We discuss the string breaking phenomenon and the relevance of avoided crossings between the fundamental string and the hadron spectrum. Good agreement with lattice data is achieved.
