Energy scan of the $e^+e^- \to h_b(nP)\pi^+\pi^-$ $(n=1,2)$ cross sections and evidence for the $\Upsilon(11020)$ decays into charged bottomonium-like states / Belle Collaboration
Using data collected with the Belle detector in the energy region of the $\Upsilon(10860)$ and $\Upsilon(11020)$ resonances we measure the $e^+e^- \to h_b(nP)\pi^+\pi^-$ $(n=1,2)$ cross sections. Their energy dependences show clear $\Upsilon(10860)$ and $\Upsilon(11020)$ peaks with a small or no non-resonant contribution. [...]

Measurement of the ratio $\Gamma(K_{L} \rightarrow \pi^{+}\pi^{-}) / \Gamma(K_{L} \rightarrow \pi^{\pm}e^{\mp}\nu)$ and extraction of the CP violation parameter $|\eta_{+-}|$ / NA48 Collaboration
We present a measurement of the ratio of the decay rates $\Gamma (K_L \rightarrow\pi^+\pi^-) / \Gamma(K_L \rightarrow\pi^{\pm}e^{\mp}\nu)$, denoted as $\Gamma_{K2\pi}/\Gamma_{Ke3}$. The analysis is based on data taken during a dedicated run in 1999 by the NA48 experiment at the CERN SPS. [...]

Measurement of the $K_{L} \to e^{+}e^{-}e^{+} e^{-}$ decay rate / NA48 Collaboration
The decay rate of the long-lived neutral $K$ meson into the $e^{+}e^{-}e^{+} e^{-}$ final state has been measured with the NA48 detector at the CERN SPS. Using data collected in 1998 and 1999, a total of 200 events has been observed with negligible background. [...]

Search for CP violation in $K^{0} \to 3\pi^{0}$ decays / NA48 Collaboration
Using data taken during the year 2000 with the NA48 detector at the CERN SPS, a search for the CP violation decay $K_{S} \to 3\pi^{0}$ has been performed. From a fit to the lifetime distribution of about 4.9 million reconstructed $K^{0}/\bar{K^{0}} \to 3\pi^{0}$ decays, the CP violationg amplitude $\eta_{000} = A(K_{S} \to 3\pi^{0})/A(K_{L} \to 3\pi^{0})$ has been found to be $\Re(\eta_{000}) = -0.002 \pm 0.011 \pm 0.015$ and Im$(\eta_{000}) -0.003 \pm 0.0013 \pm 0.017$.

Measurement of the branching ratio of the deca $K_{L} \to \pi^{\pm}e^{\mp}\nu$ and extraction of the CKM parameter $|V_{us}|$ / NA48 Collaboration
We present a new measurement of the branching ratio $R$ of the decay $K_{L} \to \pi^{\pm}e^{\mp}\nu$, denoted as $K_{e3}$, relative to all charged $K_{L}$ decays with two tracks, based on data taken with the NA48 detector at the CERN SPS. We measure $R=0.4978 \pm 0.0035$. [...]

Using data taken during the year 2000 with the NA48 detector at the CERN SPS, a search for the CP violating decay K_S -> 3 pi0 has been performed. From a fit to the lifetime distribution of about 4.9 million reconstructed K0/K0bar -> 3 pi0 decays, the CP violating amplitude eta_000 = A(K_S -> 3 pi0)/A(K_L -> 3 pi0) has been found to be Re(eta_000) = -0.002 +- 0.011 +- 0.015 and Im(eta_000) = -0.003 +- 0.013 +- 0.017.

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 $\Xi^{0} \to \Lambda\gamma$.

First observation of the $K_{S}\to \pi^{0}\gamma\gamma$ decay / NA48 Collaboration
Using the NA48 detector at the CERN SPS, 31 $K_{S}\to \pi^{0}\gamma\gamma$ candidates with an estimated background of $13.7 \pm 3.2$ events have been observed. This first observation leads to a branching ratio of $BR(K_{S}\to \pi^{0}\gamma\gamma)_{z>0.2} = (4.9 \pm 1.6_{stat} \pm 0.9_{syst}) \times 10^{-8}$ in agreement with Chiral Perturbation theory predictions..

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 $BR(K_{L} \to \pi^{+}\pi^{-}e^{+}e^{-})=(3.08 \pm 0.20) \times 10^{-7}$.
