Abstract

Using 5.2 fb-1 e+e- annihilation data samples collected with the BESIII detector, we measure the cross sections of e+e-→KS0K±π π0 and KS0K±π η at center-of-mass energies from 3.90 to 4.60 GeV. In addition, we search for the charmoniumlike resonance Y(4260) decays into KS0K±π π0 and KS0K±π η, and Zc0,±(3900) decays into KS0K±π,0 and KS0K±η. Corresponding upper limits are provided since no clear signal is observed.
