Observation of structures in the processes $e^{+}{e}^{-}\to \omega {\chi }_{c1}$ and $\omega {\chi }_{c2}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +619

We present measurements of the Born cross sections for the processes $e^{+}{e}^{-}\to \omega {\chi }_{c1}$ and $\omega {\chi }_{c2}$ at center-of-mass energies $\sqrt{s}$ from 4.308 to 4.951 GeV. The mea…
