Abstract

The NA48 collaboration has measured the amplitude of the CP-conserving component of the decay KS --> pi+ pi- pi0 relative to KL --> pi+ pi- pi0. For the characteristic parameter lambda, the values Re(lambda) = 0.038 +/-0.010 and Im(lambda) = -0.013 +/- 0.007 have been extracted. These values agree with earlier measurements and with theoretical predictions from chiral perturbation theory.
