Abstract
- We compute couplings between the ρ-meson and D and D* mesons--D(*)ρD(*)--that are relevant to phenomenological meson-exchange models used to analyze nucleon-D-meson scattering and explore the possibility of exotic charmed nuclei. Our framework is built from elements constrained by Dyson-Schwinger equation studies in QCD, and therefore expresses a simultaneous description of light- and heavy-quarks and the states they constitute. We find that all interactions, including the three independent D*ρD* couplings, differ markedly amongst themselves in strength and also in range, as measured by their evolution with ρ-meson virtuality. As a consequence, it appears that one should be cautious in using a single coupling strength or parametrization for the study of interactions between D(*) mesons and matter. [ABSTRACT FROM AUTHOR]
