I plan to devote the next years to the development of an innovative project that addresses the properties of open heavy-flavor mesons and heavy quarkonia, so-called heavy mesons, at finite temperature. This project aims at going beyond the state-of-the art using a unitarized approach in a hot medium, based on an effective hadronic theory that fulfills chiral symmetry in the light-quark sector and heavy-quark spin symmetry in the heavy-quark limit. In this manner, the properties of open heavy-flavor mesons and heavy quarkonia could be consistently and reliably applied to the analysis of transport properties as well as Euclidean correlators, so as to compare with the results coming from heavy-ion collisions and lattice QCD for heavy mesons at finite temperature.More precisely, the main scientific objectives of this proposal are:- to develop a unitarized effective hadronic theory at finite temperature fully consistent with chiral and heavy-quark QCD symmetries for temperatures below the QCD phase transition;- to determine whether newly discovered excited heavy quarkonia (charmonia and bottomonia) can be described within a molecular picture;- to evaluate transport coefficients of heavy mesons using the in-medium unitarized effective hadronic theory, cross-checking when available with results from heavy-ion collisions and lattice QCD; and- to calculate Euclidean correlators in our approach and compare them to LQCD correlators for open heavy-flavor mesons and heavy quarkonia for temperatures below the QCD phase transition.
