XVIII International Conference on Hadron Spectroscopy and Structure (HADRON2019)

Using 5.2 fb-1 e+e- annihilation data samples collected with the BESIII detector, we measure the cross sections of e+ e- -> Ks K pi pi0 and KsK pi eta at the center-of-mass energies from 3.90 to 4.60 GeV. In addition, the charmoniumlike resonance Y(4260) and Zc(3900) decay into the two decay modes are also searched for.
