Observation of the decay $D_s^{+}\to \omega {\pi }^{+}\eta$

BESIII Collaboration, M. Ablikim, M. N. Achasov +571

Using 7.33 fb${}^{-1}$ of $e^{+}{e}^{-}$ collision data collected by the BESIII detector at center-of-mass energies between 4.128 and 4.226~GeV, we observe for the first time the decay $D^…
