| Abstract: | The results are presented for the charge asymmetry of the Dalitz plot parameters g, h, and k measured for K ± → π ± π 0 π 0 decays. The experiment has been carried out in the 35-GeV/c kaon beams at the IHEP accelerator. The g, h, and k parameters appear to be identical for K + and K ? decays within the experimental uncertainty. In particular, a value of (0.2 ± 1.9) × 10?3 is obtained for the charge asymmetry A g = (g + ? g ?)/(g + + g ?) of the Dalitz plot slope. |
