Measurement of the quadratic slope parameter in the $K_{L}\rightarrow 3\pi^{0}$ decay Dalitz plot

A value of $(-6.1\pm 0.9_{stat}\pm 0.5_{syst}) \times 10^{-3}$ is obtained for the quadratic slope parameter $h$ in the $K_{L}\rightarrow 3\pi^{0}$ decay Dalitz plot at the NA48 experiment at the CERN SPS. The result is based on $14.7\times 10^{6}$ fully reconstructed $K_{L}\rightarrow 3\pi^{0} \rig...

Descripción
Sumario:A value of $(-6.1\pm 0.9_{stat}\pm 0.5_{syst}) \times 10^{-3}$ is obtained for the quadratic slope parameter $h$ in the $K_{L}\rightarrow 3\pi^{0}$ decay Dalitz plot at the NA48 experiment at the CERN SPS. The result is based on $14.7\times 10^{6}$ fully reconstructed $K_{L}\rightarrow 3\pi^{0} \rightarrow 6\gamma$ decays. This is the most precise measurement of any of the Dalitz plot slope parameters in the charged and neutral kaon decays so far.
