Ablikim, M.; Achasov, M. N.; Adlarson, P.; Ai, X. C.; Aliberti, R.; Amoroso, A.; An, M. R.; An, Q.; Bai, Y.; Bakina, O.; Balossino, I.; Ban, Y.; Bao, H. -R.; Batozskaya, V.; Begzsuren, K.; Berger, N.; Berlowski, M.; Bertani, M.; Bettoni, D.; Bianchi, F. more »

We present measurements of the Born cross sections for the processes $e^{+} e^{-} \to ω χ_{c 1}$ and $ω χ_{c 2}$ at center-of-mass energies $\sqrt{s}$ from 4.308 to 4.951 GeV. The measurements are performed with data samples corresponding to an integrated luminosity of $11.0 {fb}^{- 1}$ collected with the BESIII detector operating at the Beijing Electron Positron Collider storage ring. Assuming the $e^{+} e^{-} \to ω χ_{c 2}$ signals come from a single resonance, the mass and width are determined to be $M = (4413.6 \pm 9.0 \pm 0.8) MeV / c^{2}$ and $Γ = (110.5 \pm 15.0 \pm 2.9) MeV$ , respectively, which is consistent with the parameters of the well-established resonance $ψ (4415)$ . In addition, we also use one single resonance to describe the $e^{+} e^{-} \to ω χ_{c 1}$ line shape and determine the mass and width to be $M = (4544.2 \pm 18.7 \pm 1.7) MeV / c^{2}$ and $Γ = (116.1 \pm 33.5 \pm 1.7) MeV$ , respectively. The structure of this line shape, observed for the first time, requires further understanding.
