Abstract

A measurement of the direct CP violating charge asymmetries of the Dalitz plot linear slopes A_g=(g⁺-g^-)/(g ⁺+g^-) in K^±→π ^±π⁺π^- and K ^±→π^±π⁰π ⁰ decays by the NA48/2 experiment at CERN SPS is presented. A new technique of asymmetry measurement involving simultaneous K⁺ and K^- beams and a large data sample collected allowed a result of an unprecedented precision. The charge asymmetries were measured to be A ^c _g=(-1.5±2.2)×10^-4 with 3.11×10⁹K^±→π^±π ⁺π^- decays, and Aⁿ _g=(1. 8±1.8)×10^-4 with 9.13×10⁷K ^±→π^±π⁰π ⁰ decays. The precision of the results is limited mainly by the size of the data sample.
