Rare $\Xi^{0}$ decays: new results from NA48
The NA48 Collaboration has investigated rare decays of the $\Xi^{0}$ hyperon. Using data collected during a special high intensity run at the end of 1999, we determined the following preliminary branching fractions of the weak radiative decays to $\Lambda\gamma$ and $\Sigma^{0}\gamma:$ Br$(\Xi^{0} \...
