Abstract: (APS)

Using data samples collected by the BESIII detector operating at the BEPCII storage ring, we measure the e+e-→KS0K±π∓ 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/sn 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.

Note:

9 pages, 3 figures, and 3 tables
