New precise measurements of the $\Xi^{0} \to \Lambda \gamma$ and $\Xi^{0} \to \Sigma^{0}\gamma$ decay asymmetries
The decay asymmetries of the weak radiative Hyperon decays $\Xi^{0}\to \Lambda \gamma$ and $\Xi^{0} \to \Sigma^{0}\gamma$ have been measured with high precision using data of the NA48/1 experiment at CERN. From about 52000 $\Xi^{0}\to \Lambda \gamma$ and 15000 $\Xi^{0} \to \Sigma^{0}\gamma$ decays,...
