Measurements of e + e − → K S 0 K ± π ∓ π 0 and K S 0 K ± π ∓ η at center-of-mass energies from 3.90 to 4.60 GeV

Measurements of e + e − → K S 0 K ± π ∓ π 0 and K S 0 K ± π ∓ η at center-of-mass energies from 3.90 to 4.60 GeV

Utilizing 5.2 fb-1 e+e- annihilation data samples collected with the BESIII detector, we measure the cross sections of e+e- → K$0\atop{S}$K±$\pi$∓$\pi$0 and K$0\atop{S}$K±$\pi$∓η at center-of-mass energies from 3.90 to 4.60 GeV. In addition, we search for the charmonium-like resonance Y (4260) decay...

Zusammenfassung:Utilizing 5.2 fb-1 e+e- annihilation data samples collected with the BESIII detector, we measure the cross sections of e+e- → K$0\atop{S}$K±$\pi$∓$\pi$0 and K$0\atop{S}$K±$\pi$∓η at center-of-mass energies from 3.90 to 4.60 GeV. In addition, we search for the charmonium-like resonance Y (4260) decays into K$0\atop{S}$K±$\pi$∓$\pi$0 and K$0\atop{S}$K±$\pi$∓η, and Z$0,\atop{c}$± (3900) decays into K$0\atop{S}$K±∓$\pi$,0 and K$0\atop{S}$K±η. Corresponding upper limits are provided since no clear signal is observed.
