Strong Couplings of Three Mesons with Charm(ing) Involvement

arXiv:1609.04651 · doi:10.1051/epjconf/201713713010

Abstract

We determine the strong couplings of three mesons that involve, at least, one $η_c$ or $J/ψ$ meson, within the framework of a constituent-quark model by means of relativistic dispersion formulations. For strong couplings of $J/ψ$ mesons to two charmed mesons, our approach leads to predictions roughly twice as large as those arising from QCD sum rules.
