Abstract
We present selected results on the properties of strange and heavy-flavoured mesons in a hot and dense nuclear medium, with emphasis in selfconsistent coupled-channel approaches based on the chiral Lagrangian. In the strangeness sector, we discuss how the enhanced reactivity of light strange vectors at FAIR conditions can be tied to in-medium effects on their predominant decay modes (e.g. K̄* → K̄π) and to the excitation of strange baryons in vector-meson nucleon interactions. In the heavy-flavour sector, we focus on recent determinations of the transport coefficients of charmed and bottomed mesons in a hadron gas at vanishing baryonic chemical potential. We comment on the role of microscopic transport simulations to establish a connection between theoretical models and experimental observables from heavy-ion collisions (HICs).

The features of strongly interacting matter in a broad range of temperature and density has been a subject of great interest in the last decades, in connection with fundamental aspects of the strong interaction such as the nature ofconfinement or the physical mechanism of chiral symmetry restoration, and with the microscopic dynamics and composition of neutron stars.In particular, understanding the dynamics of light strange mesons in a nuclear environment has posed a challenge to theoretical models, amongst different reasons, due to the failure of the low-density approximation to describe the interaction of the Kmeson with the medium, as it is concluded from the phenomenology of kaonic atoms [1]
