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.eninfo:eu-repo/semantics/openAccessDECAYCHARMONIUMPrecision measurements of the e(+)e(-) -> (KSK +/-)-K-0 pi(-/+) Born cross sections at center-of-mass energies between 3.8 and 4.6 GeVArticle2-s2.0-8506519116710.1103/PhysRevD.99.072005Q1WOS:000464742000002
