Observation of Structures in the Processes e*+e*- *> *w*c&sub(c1) and *w*c&sub(c2) / M.Ablikim, O.Bakina, I.Boyko, G.Chelkov, D.Dedovich, I.Denysenko, P.Egorov, A.Guskov, Y.Nefedov, A.Sarantsev, A.Zhemchugov, [a.o.] // Physical Review Letters [Electronic resource]. – 2024. – Vol. 132, No. 16. – P. 161901. – URL: https://doi.org/10.1103/PhysRevLett.132.161901. – Bibliogr.: 31.
We present measurements of the Born cross sections for the processes e*+e*− → ω*c&sub(c1) and ω*c&sub(c2) at center- of-mass energies *%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*− → ω*c&sub(c2) signals come from a single resonance, the mass and width are determined to be M=(4413.6*( 9.0*( 0.8) MeV/c*2 and Γ =(110.5*( 15.0*( 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*− →ω*c&sub(c1) line shape and determine the mass and width to be M =(4544.2*( 18.7 *( 1.7) MeV/c*2 and Γ=(116.1 *( 33.5 *( 1.7) MeV, respectively. The structure of this line shape, observed for the first time, requires further understanding.
