The Born cross sections are measured at each energy, and a coherent fit to cross section line shape is performed using a Breit-Wigner parametrization to search for charmoniumlike vector states. No significant signals of the Y(4230) and Y(4360) resonances are observed.eninfo:eu-repo/semantics/openAccess[No Keywords]Study of e plus e- ? ?? at center-of-mass energies from 3.773 to 4.600 GeVArticle10811WOS:0011376988000062-s2.0-85182227535N/A10.1103/PhysRevD.108.112011Q1
