Abstract

The open charm mesons D-s0*(2317), D-s1(2460) and the hidden charm meson X(3872) are discussed as hadron molecules. Using a phenomenological Lagrangian approach we consider the 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. 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).
