The NA48 Collaboration has measured the amplitude of the CP-conserving component of the decay K-s(0) -> pi(+)pi(-)pi(0) relative to K-L(0) -> pi(+)pi(-)pi(0). 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.

Abstract
The NA48 Collaboration has measured the amplitude of the CP-conserving component of the decay K-s(0) -> pi(+)pi(-)pi(0) relative to K-L(0) -> pi(+)pi(-)pi(0). 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.File in questo prodotto:
