Description

We study the X(3872) → D0 anti D0π0 decay within a D anti D* molecular picture for the X(3872) state. This decay mode is more sensitive to the long-distance structure of the X(3872) resonance than its J/ψππ and J/ψ3π decays, which are mainly controlled by the details of the X(3872) wave function at short distances. We show that the D0 anti D0 final state interaction can be important, and that a precise measurement of this partial decay width can provide valuable information on the interaction strength between the D(*) anti D(*) charm mesons.
