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…

Determination of the branching ratios $I^ (K_{L} \to 3 I ¨ ^{0}) / I^ (K_{L} \to I ¨ ^{+} I ¨ ^{-} I ¨ ^{0})$ and $I^ (K_{L} \to 3 I ¨ ^{0}) / I^ (K_{L} \to I ¨ e I^½)$

A. Kreutz, M. Holder, M. Rost +27

Improved branching ratios were measured for the $K_{L} \to 3 I ¨ ^{0}$ decay in a neutral beam at the CERN SPS with the NA31 detector: $Î(K_L \to 3 Ï^0) / Î(K_L \to Ï^+ Ï^- Ï^0) =…
