Determination of the branching ratios $\Gamma(K_{L} \to 3\pi^{0}) / \Gamma(K_{L} \to \pi^{+}\pi^{-}\pi^{0})$ and $\Gamma(K_{L} \to 3\pi^{0}) / \Gamma(K_{L} \to \pi e\nu)$
Improved branching ratios were measured for the K_L \to 3 \pi^0 decay in a neutral beam at the CERN SPS with the NA31 detector:\\ \Gamma (K_L \to 3 \pi^0) / \Gamma (K_L \to \pi^+ \pi^- \pi^0) = 1.611 \pm 0.037 and\\ \Gamma (K_L \to 3 \pi^0) / \Gamma (K_L \to \pi e \nu ) = 0.545 \pm 0.010.\\ {}From t...

| description | Improved branching ratios were measured for the K_L \to 3 \pi^0 decay in a neutral beam at the CERN SPS with the NA31 detector:\\ \Gamma (K_L \to 3 \pi^0) / \Gamma (K_L \to \pi^+ \pi^- \pi^0) = 1.611 \pm 0.037 and\\ \Gamma (K_L \to 3 \pi^0) / \Gamma (K_L \to \pi e \nu ) = 0.545 \pm 0.010.\\ {}From the first number an upper limit for \Delta I =5/2 and \Delta I = 7/2 transitions in neutral kaon decay is derived. Using older results for the Ke3/K\mu 3 fraction, the 3\pi^0 branching ratio is found to be \Gamma (K_L \to 3 \pi^0 )/ \Gamma_{tot} = (0.211 \pm 0.003), about a factor three more precise than from previous experiments.\\[1ex] |
