Measurement of the charge asymmetry of the Dalitz plot parameters for K ± → π ± π 0 π 0 decays

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.
