Heavy meson production in hot dense matter

TL;DR

This paper investigates how charmed mesons behave in dense nuclear matter using a coupled-channel approach, revealing their spectral functions and implications for resonances and mesic nuclei formation.

Contribution

It introduces a self-consistent method to study charmed mesons in dense matter, accounting for Pauli-blocking and meson self-energies, advancing understanding of their properties in such environments.

Findings

Charmed meson spectral functions are computed in dense nuclear matter.

Implications for hidden charm and scalar resonances are discussed.

Potential formation of D-mesic nuclei at FAIR energies is analyzed.

Abstract

The properties of charmed mesons in dense matter are studied using a unitary coupled-channel approach in the nuclear medium which takes into account Pauli-blocking effects and meson self-energies in a self-consistent manner. We obtain the open-charm meson spectral functions in this dense nuclear environment, and discuss their implications on hidden charm and charm scalar resonances and on the formation of $D$-mesic nuclei at FAIR energies.
