Abstract
Using data samples collected by the BESIII detector operating at the BEPCII storage ring, we measure the e(+)e(-) -> (KSK +/-)-K-0 pi(-/+ )Born cross sections at center-of-mass energies between 3.8 and 4.6 GeV, corresponding to a luminosity of about 5.0 fb(-1). The results are compatible with the BABAR measurements, but with the precision significantly improved. A simple 1/s(n) dependence for the continuum process can describe the measured cross sections, but a better fit is obtained by an additional resonance near 4.2 GeV, which could be an excited charmonium or a charmoniumlike state.
