Study of the Dalitz plot of the $\eta \to {\pi }^{+}{\pi }^{-}{\pi }^0$ decay with the KLOE detector

The decay $\eta \to {\pi }^{+}{\pi }^{-}{\pi }^0$ is studied with the KLOE detector, at the DA$\varphi$NE e${}^{+}$e${}^{-}$ collider. Using a data sample corresponding to an integrated luminosity of $1.6$ fb${}^{-1}$ a new study of the Dalitz plot is presented.
