Charmed mesons in nuclear matter

TL;DR

This paper investigates the properties of charmed mesons in dense nuclear matter using a coupled-channel approach, revealing their in-medium behavior and implications for scalar resonances and mesic nuclei formation.

Contribution

It introduces a self-consistent coupled-channel method to study charmed mesons and baryonic resonances in dense matter, accounting for Pauli blocking and meson self-energies.

Findings

Modified properties of open-charm mesons in dense matter.

Implications for the $D_{s0}(2317)$ and X(3700) resonances.

Predictions for $D$-mesic nuclei formation.

Abstract

We obtain the properties of charmed mesons in dense matter using a coupled-channel approach which accounts for Pauli blocking effects and meson self-energies in a self-consistent manner. We study the behaviour of dynamically-generated baryonic resonances together with the open-charm meson spectral functions in this dense nuclear environment. We discuss the implications of the in-medium properties of open-charm mesons on the $D_{s0}(2317)$ and the predicted X(3700) scalar resonances, and on the formation of $D$-mesic nuclei.
