Observation of the $W$-annihilation process $D_s^{+}\to \omega {\rho }^{+}$ and measurement of $D_s^{+}\to \varphi {\rho }^{+}$ in $D_s^{+}\to {\pi }^{+}{\pi }^{+}{\pi }^{-}{\pi }^0{\pi }^0$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

We present the first amplitude analysis and branching fraction measurement of the decay $D_s^{+}\to {\pi }^{+}{\pi }^{+}{\pi }^{-}{\pi }^0{\pi }^0$, using $e^{+}{e}^{-}$ collision data collected with the BESIII detector…
