摘要：
The results are presented for the charge asymmetry of the Dalitz plot parameters g, h, and k measured for K+/- -> pi(+/-)pi(0)pi(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) x 10(-3) is obtained for the charge asymmetry A(g) = (g(+) - g(-))/(g(+) + g(-)) of the Dalitz plot slope. (c) 2005 Pleiades Publishing, Inc.
