On temperature dependence of quarkonium correlators

Abstract

I discuss the temperature dependence of quarkonium correlators calculated in lattice QCD. I show that the dominant source of the temperature dependence comes from the zero mode contribution, while the the temperature dependence associated with melting of bound states is quite small. I study the zero mode contribution quantitatively for different quark masses and show that it is well described by a quasi-particle model with temperature dependent heavy quark mass. As a byproduct an estimate of the medium dependence of the heavy quark mass is obtained.
