Until two decades ago, it was widely believed that hadron resonances with masses higher than the open-charm (OC) pair thresholds decay entirely to OC final states via the strong interaction. However, in July, 2003, BES reported the observation of seven events of hadron reso- nance(s) in this mass regime decaying to nOCH [1–4]. This discovery overturned the understanding of resonance decays and opened up a new era in hadron spectroscopy.
