Measurement of the $\hat{I}\cdot \to \ddot{I}{€}^{+}\ddot{I}{€}^{-}\ddot{I}{€}^0$ Dalitz plot distribution

Abstract

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