Abstract
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 heavylight 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. We report our results for the ground-state thermal spectral functions and the implications for the excited mesonic states generated dynamically in the heavy-light molecular model. We have applied these to the calculation of meson Euclidean correlators and transport coefficients for D mesons and summarize here our findings.

Heavy-ion collision experiments in the Relativistic Heavy Ion Collider (RHIC), at BNL, and in the Large Hadron Collider (LHC), at CERN, recreate in the laboratory the conditions for which the quark-gluon plasma (QGP) was created in the early Universe, short after the BigBang

Summary
Heavy-ion collision experiments in the Relativistic Heavy Ion Collider (RHIC), at BNL, and in the Large Hadron Collider (LHC), at CERN, recreate in the laboratory the conditions for which the quark-gluon plasma (QGP) was created in the early Universe, short after the Big. The spectral properties of the open heavy-flavor mesons are modified in the hot hadronic medium from their interaction with the light mesons forming the medium. Ds within a unitarized thermal approach in [1, 2] This framework exploits both chiral symmetry and heavy-quark spin-flavor symmetry (HQSFS) to construct the e↵ective Lagrangian that describes the interactions between the heavy and light degrees in vaccuum. The e↵ective theory results for the thermal scattering amplitudes and the spectral functions were used to compute open-charm meson Euclidean correlators in Ref. Further details can be found in Refs.
