Measurement of the $\Xi^{0} \to \Lambda\gamma$ decay asymmetry and branching fraction / NA48 Collaboration
In data taken with the NA48 experiment at the CERN SPS in 1999, 730 candidates of the weak radiative hyperon decay $\Xi^{0} \to \Lambda\gamma$ have been found with an estimated background of $58 \pm 8$ events. From these events the $\Xi^{0} \to \Lambda\gamma$ decay asymmetry has been determined to $\alpha(\Xi^{0} \to \Lambda\gamma) = -0.78 \pm 0.18_{stat} \pm 0.06_{syst}$, which is the first evidence of a decay asymmetry in $\Xi^{0} \to \Lambda\gamma$.

Investigation of $K_{L,S} \rightarrow \pi^{+}\pi^{-}e^{+}e^{-}$ decays / NA48 Collaboration
The $K_{L} \to \pi^{+}\pi^{-}e^{+}e^{-}$ and $K_{S} \to \pi^{+}\pi^{-}e^{+}e^{-}$ decay modes have been studied in detail using the NA48 detector at CERN SPS. Based on the data collected during the 1998 and 1999 run periods, a sample of 1162 $K_{L} \to \pi^{+}\pi^{-}e^{+}e^{-}$ candidates has been observed with an expected background level of 36.9 events, yielding the branching ratio measurement $BR(K_{L} \to \pi^{+}\pi^{-}e^{+}e^{-})=(3.08 \pm 0.20) \times 10^{-7}$.

Search for the decay $K_{S} \to \pi^{0}e^{+}e^{-}$ / NA48 Collaboration
A search for the decay $K_{S} \to \pi^{0}e^{+}e^{-}$ has been made using the NA48 detector at the CERN SPS. Using data collected in 1999 during a 40-hour run with a high-intensity $K_{S}$ beam, an upper limit for the branching fraction ${\rm B}(K_{S} \to \pi^{0}e^{+}e^{-}) < 1.4 \times 10^{-7}$ at 90\% confidence level has been obtained..

Precision measurement of the $\Xi^{0}$ mass and the branching ratios of the decays $\Xi^{0}\rightarrow\Lambda\gamma$ and $\Xi^{0}\rightarrow\Sigma^{0}\gamma$ / NA48 Collaboration
A new precision measurement of the $\Xi^{0}$ mass has been performed at the NA48 experiment at the CERN SPS. The value obtained is $[1314.82 \pm 0.06_{(stat.)} \pm 0.2_{(syst.)}]$MeV/c$^{2}$. [...]
