摘要

As the first confirmed charged charmoniumlike state, Zc(3900) was first reported by the BESIII[1] and Belle[2] Collaborations in the J/ π± invariant mass spectrum of e+e?!+?J/ at 4.26 GeV. The CLEO Collaboration confirmed the existence of the Zc(3900)± in the same process but at 4.17 GeV and the neutral Zc(3900) was also reported with a 3σ significance[3].
