Hadron molecules

    Corresponding author: Thomas Gutsche,

Abstract: 

We discuss a possible interpretation of the open charm mesons Ds0*(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 Ds0*(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/ψ 2π 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+ω or J/ψ+φ, respectively.
