Study of Hadronic Five-Body Decays of Charmed Mesons Involving $K_S^0$

the FOCUS Collaboration, J. M. Link

We study the decay of $D^0$ and $D_s^{+}$ mesons into five-body final states including a $K_S^0$ and report the discovery of the decay mode $D_s^{+}\to K_S^0{K}_S^0{\pi }^{+}{\pi }^{+}{\pi }^{-}$. The branc…
