VALUE ($ 10^{-3} $) DOCUMENT ID TECN $1.596$ $\pm0.013$ 1 AMBROSINO 2006 H KLOE • • We do not use the following data for averages, fits, limits, etc. • • $1.664$ $\pm0.010$ 2 LAI 2005 A NA48 1  AMBROSINO 2006H uses Bell-Steinberger relations with the following measurements: B( ${{\mathit K}_L^0}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ ) in AMBROSINO 2006F, B( ${{\mathit K}_S^0}$ $\rightarrow$ ${{\mathit \pi}^{0}}{{\mathit \pi}^{0}}{{\mathit \pi}^{0}}$ ) in AMBROSINO 2005B, the ${{\mathit K}_S^0}$ -semileptonic charge asymmetry in AMBROSINO 2006E, and ${{\mathit K}^{0}}$-semileptonic results in ANGELOPOULOS 1998F. 2  LAI 2005A values are obtained through unitarity (Bell-Steinberger relations), improving determination of $\eta _{000}$ and combining other data from PDG 2004 and APOSTOLAKIS 1999B.
