Measurements of e(+)e(-)-> (KSK +/-)-K-0 pi(-/+)pi(0)and (KSK +/-)-K-0 pi(-/+)eta at center-of-mass energies from 3.90 to 4.60 GeV

Abstract

Using 5.2 fb(-1) e(+)e(-) annihilation data samples collected with the BESIII detector, we measure the cross sections of e(+)e(-)->(KSK +/-)-K-0 pi(-/+)pi(0) and (KSK +/-)-K-0 pi(-/+)eta at center-of-mass energies from 3.90 to 4.60 GeV. In addition, we search for the charmoniumlike resonance Y(4260) decays into (KSK +/-)-K-0 pi(-/+)pi(0) and (KSK +/-)-K-0 pi(-/+)eta and Z(c)(0,+/-) (3900) decays into (KSK +/-)-K-0 pi(-/+,0) and (KSK +/-)-K-0 eta. Corresponding upper limits are provided since no clear signal is observed.
