Measurements of e ~+ e ~- → K_S~0K~±π~?π~0 and K_S~0K~±π~?η at center-of-mass energies from 3.90 to 4.60 GeV

摘要

Using 5.2 fb~(-1) e~+e~- annihilation data samples collected with the BESIII detector, we measure the cross sections of e~+e~- → K_S~0K~±π~?π~0 and K_S~0K~±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 K_S~0K~±π~?π~0 and K_S~0K~±π~?η, and Z_c~(0,±) (3900) decays into K_S~0K~±π~(?,0) and K_S~0K~±η. Corresponding upper limits are provided since no clear signal is observed.
