Properties of D-mesons in nuclear matter within a self-consistent coupled-channel approach
Abstract
The spectral density of the -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 interaction, described through a G-matrix, generates dynamically the (2593) resonance. This resonance is the charm counterpart of the (1405) resonance generated from the s-wave 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 -meson results in an overall reduction of the in-medium -meson changes compared to previous work which neglect those effects.
