Abstract

Preliminary results of study of K^±→3π^± decays by the NA48/2 experiment at CERN SPS are presented. They include a precise measurement of the direct CP violating charge asymmetry of Dalitz plot linear slope parameters A_g=(g⁺-g^-)/(g⁺+g^-), and a measurement of the Dalitz plot slope parameters (g,h,k) themselves. Due to the design of the experiment, and a large data set collected, unprecedented precisions were achieved.
