Measurement of $e^{+} e^{-} \to η J / ψ$ Cross Section from $s =$ 3.808 GeV to 4.951 GeV

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

Using data samples with an integrated luminosity of 22.42 fb $^{- 1}$ collected by the BESIII detector operating at the BEPCII storage ring, we measure the cross sections of the $e^{…
