Hadrons with charmed quarks in matter

Article

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.
