Abstract

We discuss the interpretation of the open charm mesons D*(s0)(2317), D-s1(2460) and the hidden charm meson X(3872) as hadron molecules. Using a phenomenological Lagrangian approach we consider strong and radiative decays of the D*(s0)(2317) and D-s1(2460) states. The X(3872) is assumed to consist dominantly of molecular hadronic components with an additional small admixture of a charmonium configuration. A potential model based on meson-exchange is able to generate weak binding of the molecular hadronic components. The observed radiative (gamma J/Psi and gamma Psi(2s)) and strong (J/Psi 2 pi and J/Psi 3 pi decays are shown to be consistent with the molecular structure assumption of the X(3872).
