Study of the reactions $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\pi }^0{\pi }^0{\pi }^0{\pi }^0$ and ${\pi }^{+}{\pi }^{-}{\pi }^0{\pi }^0{\pi }^0\eta$ at center-of-mass energies from threshold to 4.5 GeV using initial-state radiation

BaBar Collaboration

We study the processes $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\pi }^0{\pi }^0{\pi }^0{\pi }^0\gamma$ and $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\pi }^0{\pi }^0{\pi }^0\eta \gamma$ in which an energetic photon is radiated from the initial state. The data were collected with…
