title = "Cross section measurements of e+e- →ωχc0 from s =4.178 to 4.278 GeV CROSS SECTION MEASUREMENTS of ⋯ M. ABLIKIM et al.",
abstract = "The cross section of the process e+e-→ωχc0 is measured at center-of-mass energies from s=4.178 to 4.278 GeV using a data sample of 7 fb-1 collected with the BESIII detector operating at the BEPCII storage ring. The dependence of the cross section on s shows a resonant structure with mass of (4218.5±1.6(stat)±4.0(syst)) MeV/c2 and width of (28.2±3.9(stat)±1.6(syst)) MeV, respectively. This observation confirms and improves upon the result of a previous study. The angular distribution of the e+e-→ωχc0 process is extracted for the first time.",
