Measurement of the Born cross section for $e^{+}{e}^{-}\to \eta h_c$ at center-of-mass energies between 4.1 and 4.6\,GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +644

We measure the Born cross section for the reaction $e^{+}{e}^{-}\to \eta h_c$ from $\sqrt{s}=4.129$ to $4.600$~GeV using data sets collected by the BESIII detector running at…
