Properties of D mesons in nuclear matter within a self-consistent coupled-channel approach -: art. no. 025203

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 Lambda(c)(2593) resonance. This resonance is the charm counterpart of the Lambda(1405) resonance generated from the s-wave (K) over barN 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 neglected those effects.
