Observation of $\psi (4415)\to D\bar{D}{}_2^{\ast }(2460)$ decay using initial-state radiation

Belle Collaboration, G. Pakhlova

We report the first observation of the $\psi (4415)$ resonance in the reaction $\e^+e^-\to D^0 D^-π^+$ and a measurement of its cross section in the center-of-mass energy range $4.0\ma…
