Measurement of the branching ratio of the decay $I^^{0} \to I^£^{+} I^¼^{-} I^ˉ ½_{I^} ¼$

J. R. Batley, G. E. Kalmus, C. Lazzeroni +110

From the 2002 data taking with a neutral kaon beam extracted from the CERN-SPS, the NA48/1 experiment observed 97 $I^^{0} \to I^£^{+} I^¼^{-} I^ˉ ½_{I^} ¼$ candidates with a back…

Empirical parameterization of the K+- -> pi+- pi0 pi0 decay Dalitz plot

J. R. Batley, A. J. Culling, G. Kalmus +118

As first observed by the NA48/2 experiment at the CERN SPS, the $\p0p0$ invariant mass (M00) distribution from $\kcnn$ decay shows a cusp-like anomaly at M00=2m+, where m+ is the c…

ChPT tests at the NA48 and NA62 experiments at CERN

NA48/2, NA62 Collaborations, : +159

The NA48/2 Collaboration at CERN has accumulated unprecedented statistics of rare kaon decays in the Ke4 modes: Ke4(+-) ( $K^{\pm} \to I ¨ ^{+} I ¨ ^{-} e^{\pm} I^½$ ) and Ke4(00) ($K^\pm \to Ï^…

Recent NA48/2 and NA62 results

F. Ambrosino, A. Antonelli, G. Anzivino +156

The NA48/2 Collaboration at CERN has accumulated and analysed unprecedented statistics of rare kaon decays in the $K_{e 4}$ modes: $K_{e 4} (+ -)$ ( $K^{\pm} \to I ¨ ^{+} I ¨ ^{-} e^{\pm} I^½$ ) and…
