Binding of D, D-bar and J/Psi mesons in nuclei

TL;DR

This paper estimates the potentials of D, anti-D, and J/Psi mesons in nuclei, finding that J/Psi and D- mesons can form bound states within nuclear matter due to attractive interactions.

Contribution

It introduces a novel calculation of J/Psi meson potential in nuclei based on the color-singlet mechanism, including in-medium effects of D and D* mesons.

Findings

J/Psi potential is attractive and complementary to gluon-based mechanisms.

D- and J/Psi mesons are predicted to form bound states in nuclei.

The study incorporates in-medium properties of D and D* mesons.

Abstract

We estimate the $D$, $\overline{D}$ and $J/\Psi$ meson potentials in nuclei. $J/\Psi$-nuclear potential (self-energy) is calculated based on the color-singlet mechanism, by the $DD$ and $DD^*$ meson loops. This consistently includes the in-medium properties of $D$ and $D^*$ mesons. The potential obtained for the $J/\Psi$ meson is attractive, and it is complementary to the attraction obtained from the color-octet gluon-based mechanism. We predict that the $D^-$ and $J/\Psi$ mesons will be bound in nuclei under proper conditions.
