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:
