Measurement of the $\eta \to {\pi }^{+}{\pi }^{-}{\pi }^0$ Dalitz plot distribution

Abstract

Dalitz plot distribution of the $\eta \to {\pi }^{+}{\pi }^{-}{\pi }^0$ decay is determined using a data sample of $1.2\cdot 10^7$ $\eta$ mesons from $pd{\to }^3\text{He}\eta$ reaction at 1 GeV collected by the WASA detector at COSY.
