Abstract
We report the observation of two narrow structures in the mass spectra of the (, 2, 3) and (, 2) pairs that are produced in association with a single charged pion in decays. The measured masses and widths of the two structures averaged over the five final states are , , and , . The results are obtained with a data sample collected with the Belle detector in the vicinity of the resonance at the KEKB asymmetric-energy collider.
