Charmed hadrons in nuclear medium

TL;DR

This paper investigates how charmed hadrons behave in dense nuclear matter using a coupled-channel approach, revealing modifications in resonances and meson properties with implications for specific scalar states.

Contribution

It introduces a self-consistent coupled-channel framework to study in-medium properties of charmed hadrons, including baryonic resonances and open-charm mesons.

Findings

Dynamically-generated baryonic resonances are modified in dense matter.

Open-charm meson spectral functions are significantly affected by the medium.

Implications for the properties of D_{s0}(2317) and X(3700) resonances are discussed.

Abstract

We study the properties of charmed hadrons in dense matter within a coupled-channel approach which accounts for Pauli blocking effects and meson self-energies in a self-consistent manner. We analyze the behaviour in this dense environment of dynamically-generated baryonic resonances as well as the open-charm meson spectral functions. 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.
