Abstract

We compute couplings between the.-meson and D and D{*} mesons-Dd(({*}))rho D-({*})-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 DysonSchwinger 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{*}rho D{*} couplings, differ markedly amongst themselves in strength and also in range, as measured by their evolution with rho-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. (AU)
