Observation of $e^{+}{e}^{-}\to \eta h_c$ at center-of-mass energies from 4.085 to 4.600 GeV

BESIII collaboration, M. Ablikim, M. N. Achasov +425

We observe for the first time the process $e^{+}{e}^{-}\to \eta h_c$ with data collected by the BESIII experiment. Significant signals are observed at the center-of-mass energy…
