摘要：Since the discovery of X(3872) in 2003, the studiesof the exotic resonances with heavy flavor turn to be extremely significant inboth theoretical and experimental investigations. Among these exotic resonances, the charged charmonium-like states Zc(3900) and Zc(4020) are very famous. Recently, the BESIII Collaboration reported a new measurement of the ηcρ decay mode of the two Zc states.In this talk, I will present our investigations on the decays of Zc(3900) and Zc(4020) and give our view of theirs inner structure.Besides, I will briefly discuss the theirproductionmechanism.
