Abstract
We study the possibility that the state observed by Belle is a (or ) resonance in S-wave. Focusing on its decays, We find that the open-charm decay into is dominant. Furthermore, we use the re-scattering mechanism to study its hidden-charm decays and find that the re-scattering effects are significant in channel but not in channel. For the candidate, with chosen parameters, we can get , which tends to account for why the is difficult to be found in . However, the candidate can not be ruled out by our calculations.
