Heavy flavor hadron molecules

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 (γJ/Ψ and γΨ(2s)) and strong (J/Ψ2π and J/Ψ3π) decays are shown to be consistent with the molecular structure assumption of the X(3872).
