We have developed a self-consistent theoretical approach to study the modification of the properties of heavy mesons in hot mesonic matter which takes into account chiral and heavy-quark spin-flavor symmetries. The heavy-light meson-meson unitarized scattering amplitudes in coupled channels incorporate thermal corrections by using the imaginary-time formalism, as well as the dressing of the heavy mesons with the self-energies [1, 2]. As a result, the open heavy-flavour ground-state spectral functions broaden and their peak is shifted towards lower energies with increasing temperatures. I will discuss the implications for the excited mesonic states generated dynamically in this heavy-light molecular model. In addition I will show meson Euclidean correlators calculated using the thermal ground-state spectral functions obtained with this methodology and their comparison with recent open-charm lattice correlators [3].
