Measurements of the Charge Asymmetry of the Dalitz Plot Parameters for $K^{\pm }\to {\pi }^{\pm }{\pi }^0{\pi }^0$ Decays

Abstract

The charge asymmetry of the g, h, and k Dalitz plot parameters for $K^{\pm }\to {\pi }^{\pm }{\pi }^0{\pi }^0$ 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 $K^{\pm }\to {\pi }^{\pm }{\pi }^0{\pi }^0$ decays within the errors quoted. In particular, the charge asymmetry $A_g=(g^{+}-g^{-})/(g^{+}+g^{-})$ of the slope g is equal to $(0.2\pm 1.9)\cdot 10^{-3}$.
