Abstract.
The charge asymmetry of the g, h, and k Dalitz plot parameters for \({K^{\pm}\rightarrow \pi^{\pm} \pi^{0} \pi^{0}}\) decays has been measured with 35 GeV/c hadron beams at the 70 GeV IHEP accelerator. The g, h, and k values obtained appear to be identical for \(K^{\pm}\) decays within the errors quoted. In particular, the charge asymmetry A g = (g + – g -)/(g + + g -) of the slope g is equal to \({(0.2 \pm 1.9)\cdot 10^{-3}}\).
