Hadrons with charmed quarks in matter

Abstract

We investigate the $D\bar{D}$ decay width of excited charmonium states at finite nuclear density with simultaneous modification of both $D$ and $\bar{D}$ mesons in nuclear matter. The strongest effect is found for the ${\Psi }^{\prime }$ meson. The medium modification can be detected by dilepton spectroscopy as substantial ${\Psi }^{\prime }$ broadening and anomalous ${\Psi }^{\prime }$ absorption.
