Search for $X(1870)$ via the decay $J/\psi \to \omega K^{+}{K}^{-}\eta$

BESIII Collaboration, M. Ablikim, M. N. Achasov +649

Using a sample of $(10087\pm 44)\times 10^6$ $J/\psi$ events collected by the BESIII detector at the BEPCII collider, we search for the decay $X(1870)\to K^{+}{K}^{-}\eta$ via the $J/ψ\to ωK…
