IN this work, we perform a full amplitude analysis of the process , where refers to either or . A new charmoniumlike state that decays to is determined with a significance of . Its mass is , and its width is . The hypothesis is favored over the hypothesis at the level of . The analysis is based on the data sample collected by the Belle detector at the asymmetric-energy collider KEKB.
