We have chosen a representative value of η = 0 . 1 GeV − 2 and show results for fixed bare and effective charm mass. 

Clearly, dissipative effects due to the medium change the mesonic correlators measured in lattice simulations. Also, these effects are not trivial: holding the effective charm mass fixed but varying η still leads to changes in the mesonic correlators. The next step is to perform spectral analysis of these correlators to examine how dissipation affects the spectral function for this correlator. From here, the dissipative effects can be included in heavy-ion phenomenology. 

## IV. CONCLUSIONS 

We have taken the approach of Caldeira and Leggett and determined an imaginary-time path integral, representing the reduced density matrix for a dissipative system, which con- tains integrals that are convergent and therefore suitable for numerical integration. We have shown how interactions with the QCD medium above deconfinement can affect Euclidean heavy-heavy correlators. 

The purpose of this paper is only to identify this effect. In order to achieve a result which
