Abstract

We discuss a, possible interpretation of the open charm mesons D s0* (2317), Ds1 (2460) and the hidden charm mesons X(3872), Y(3940) and Y(4140) as hadron molecules. Using a, phenomenological Lagrangian approach we review the strong and radiative decays of the D s0* (2317) and Ds1 (2460) states. The X(3872) is assumed to consist dominantly of molecular hadronic components with an additional small admixture of a charmonium configuration. Determing the radiative (γJ/Ψ and γΨ (2s)) and strong (J/Ψ2π and J/Ψ 3π) decay modes we show that the present experimental observation is consistent with the molecular structure assumption of the X(3872). Finally, we give evidence for molecular interpretations of the Y(3940) and Y(4140) related to the observed strong decay modes J/Ψ + w or J/Ψ + Φ, respectively.
