The Beam and detector for the NA48 neutral kaon CP violation experiment at CERN / NA48 Collaboration
The beam and detector, used for the NA48 experiment, devoted to the measurement of $\Re(\epsilon^{\prime}/\epsilon)$, and for the NA48/1 experiment on rare $K_{S}$ and neutral hyperon decays, are described..

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. [...]

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 $R=0.4978 \pm 0.0035$. [...]

Search for the decay $K_{S} \to \pi^{0} \gamma\gamma$ / NA48 Collaboration
A search for the decay $K_{S} \to \pi^{0} \gamma\gamma$ 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 ratio $BR(K_{S} \to \pi^{0} \gamma\gamma, z \geq 0.2) < 3.3 \times 10^{-7}$ has been obtained at 90% confidence level, where $z = m_{\gamma\gamma}^{2}/m_{K_{0}}^{2}$..

A measurement of the $K_{S}$ lifetime / NA48 Collaboration
A measurement of the $K_{S}$ lifetime is presented using data recorded by the NA48 experiment at the CERN-SPS during 1998 and 1999. The $K_{S}$ lifetime is derived from the ratio of decay time distributions in simultaneous, collinear $K_{S}$ and $K_{L}$ beams, giving a result which is approximately independent of the detector acceptance and with reduced systematic errors.

A precise measurement of the direct CP violation parameter $\Re(\epsilon'/\epsilon)$ / NA48 Collaboration
The direct CP violation parameter $\Re(\epsilon'/\epsilon)$ has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. With 3.3 million $K_{L} \to \pi^{0}\pi^{0}$ events collected during the 1998 and 1999 running periods, a result of $\Re(\epsilon'/\epsilon) = (15.0 \pm 2.7) \times 10^{-4}$ has been obtained. [...]
