Dalitz plot analyses of $J/\psi \to {\pi }^{+}{\pi }^{-}{\pi }^0$, $J/\psi \to K^{+}{K}^{-}{\pi }^0$, and $J/\psi \to K_S^0{K}^{\pm }{\pi }^{\mp }$ produced via $e^{+}{e}^{-}$ annihilation with initial-state radiation

The BaBar Collaboration

We study the processes $e^{+}{e}^{-}\to {\gamma }_{\mathrm{ISR}}J/\psi$ where $J/\psi \to {\pi }^{+}{\pi }^{-}{\pi }^0$, $J/\psi \to K^{+}{K}^{-}{\pi }^0$, and $J/\psi \to K_S^0{K}^{\pm }{\pi }^{\mp }$ using a data sample of 519 $f{b}^{-1}$ rec…
