The spectral density of the D-meson in the nuclear environment is studied
within a self-consistent coupled-channel approach assuming a separable
potential for the bare meson-baryon interaction. The DN interaction,
described through a G-matrix, generates dynamically the Λc (2593)
resonance. This resonance is the charm counterpart of the Λ (1405)
resonance generated from the s-wave KˉN interaction in the I=0 channel.
The medium modification of the D-meson spectral density due to the Pauli
blocking of intermediate states as well as due to the dressing of the D-mesons,
nucleons and pions is investigated. We observe that the inclusion of
coupled-channel effects and the self-consistent dressing of the D-meson
results in an overall reduction of the in-medium D-meson changes compared to
previous work which neglect those effects.Comment: 23 pages, 10 figures, submitted for publicatio
