Heavy mesons in dense matter

TL;DR

This paper investigates how charmed mesons behave in dense 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 open-charm mesons in dense matter, incorporating Pauli-blocking and meson self-energies.

Findings

Charmed meson spectral functions are significantly modified in dense matter.

Implications for hidden charm and scalar resonances are discussed.

Potential formation of D-mesic nuclei in dense environments.

Abstract

Charmed mesons in dense matter are studied within a unitary coupled-channel approach 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 medium, and discuss their implications on hidden charm and charm scalar resonances and on the formation of D-mesic nuclei.
