Study of the process $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}\eta$ using initial state radiation

The BABAR Collaboration

We study the process $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}\eta \gamma$, where the photon is radiated from the initial state. About 8000 fully reconstructed events of this process are selected from the BaBar d…
