Strong Couplings of Three Mesons with Charm(ing) Involvement
Abstract
We determine the strong couplings of three mesons that involve, at least, one ηc or J/ meson, within the framework of a constituent-quark model by means of relativistic dispersion formulations. For strong couplings of J/ mesons to two charmed mesons, our approach leads to predictions roughly twice as large as those arising from QCD sum rules.
