Description
A precise search for direct CP-violation in K±→π±π0π0 decays was performed by the NA48/2 experiment at CERN SPS. The asymmetry in the Dalitz plot linear slopes is measured to be Ag=(2.1±1.9)·10-4 by studying ∼91·106 events. The unique double-beam system, the design of the detectors and the method of analysis provide good control of the instrumental charge asymmetries and allow one to keep the precision of the result limited by statistics
