This decay mode is more sensitive to the long-distance structure of the resonance than its and decays, which are mainly controlled by the details of the wave function at short distances. We show that the 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 charm mesons. %R 10.1140/epjc/s10052-014-2885-4 %U http://arxiv.org/abs/arXiv:1404.1776 %U https://doi.org/10.1140/epjc/s10052-014-2885-4 %P 2885 - 10pp
