Search for Direct CP Violation in K+-->pi+-pi+pi- Decays by NA48/2
I. Mikulec
Abstract
First preliminary measurement of the direct CP-violating parameter Ag by the NA48/2 experiment at CERN SPS is presented. Using more than 1.6 billions of charged kaon decays into three charged pions, the charge asymmetry in the K+-->pi+-pi+pi- Dalitz plot slope, Ag, has been measured to Ag = (0.5 +- 3.8) x 10-4. This result is more than an order of magnitude more precise than results of previous experiments.
