First observation and study of the $K^{\pm} \rightarrow \pi^{0} \pi^{0} \mu^{\pm} \nu$ decay / NA48/2 Collaboration
The NA48/2 experiment at CERN reports the first observation of the $K^{\pm} \rightarrow \pi^{0} \pi^{0} \mu^{\pm} \nu$ decay based on a sample of 2437 candidates with 15% background contamination collected in 2003-2004. The decay branching ratio in the kinematic region of the squared dilepton mass above $0.03$~GeV$^2/c^4$ is measured to be $(0.65 \pm 0.03) \times 10^{-6}$. [...]

Measurement of the form factors of charged kaon semileptonic decays / NA48/2 Collaboration
A measurement of the form factors of charged kaon semileptonic decays is presented, based on $4.4 \times 10^{6}$ $K^\pm \to \pi^0 e^\pm \nu_e$ ($K^\pm_{e3}$) and $2.3 \times 10^{6}$ $K^\pm \to \pi^0 \mu^\pm \nu_\mu$ ($K^\pm_{\mu3}$) decays collected in 2004 by the NA48/2 experiment. The results are obtained with improved precision as compared to earlier measurements. [...]

First observation and measurement of the decay $K^{\pm} \to\pi^{\pm}e^{+}e^{-}\gamma$ / NA48/2 Collaboration
Using the full data set of the NA48/2 experiment, the decay $K^{\pm} \rightarrow \pi^{\pm} e^{+} e^{-}\gamma$ is observed for the first time, selecting 120 candidates with $7.3 \pm 1.7$ estimated background events. With $K^{\pm} \rightarrow \pi^{\pm} \pi^{0}_{D}$ as normalisation channel, the branching ratio is determined in a model-independent way to be Br$(K^{\pm} \rightarrow \pi^{\pm} e^{+} e^{-}\gamma, m_{ee\gamma} > 260$ MeV/c$^{2}) = (1.19 \pm 0.12_{stat} \pm 0.04_{syst}) \times 10^{-8}$.

New high statistics measurement of $K_{e4}$ decay form factors and $\pi\pi$ scattering phase shifts / NA48/2 Collaboration
We report results from a new measurement of the $K_{e4}$ decay $K^{\pm} \rightarrow \pi^{+}\pi^{-}e^{\pm}\nu$ by the NA48/2 collaboration at the CERN SPS, based on a partial sample of more than 670000 $K_{e4}$ decays in both charged modes collected in 2003. The form factors of the hadronic current (F, G, H) and $\pi\pi$ phase difference ($\delta=\delta_{s}-\delta_{p}$) have been measured in ten independent bins of the $\pi\pi$ mass spectrum to investigate the variation. [...]

Determination of the relative decay rate $K_{S} \to \pi e \nu$ / $K_{L} \to \pi e \nu$ / NA48 Collaboration
The decay rate of $K_{S} \to \pi e \nu$ relative to the rate of $K_{L} \to \pi e \nu$ has been measured by the NA48 collaboration in a neutral Kaon beam originating from 400 GeV proton-Be interactions at the CERN SPS. The result is $0.993 \pm 0.026_{stat} \pm 0.022_{syst}$, compatible with 1 in agreement with the Standard Model prediction at tree level. [...]

Search for direct CP-violation in $K^{\pm} \to \pi^{\pm} \pi^{0} \pi^{0}$ decays / NA48/2 Collaboration
A search for direct CP-violation in $K^{\pm}\rightarrow \pi^\pm \pi^0 \pi^0$ decay based on 47.14 million events has been performed by the NA48/2 experiment at the CERN SPS. The asymmetry in the Dalitz plot linear slopes $A_g = ( g^+ -g^- ) / ( g^+ + g^- )$ is measured to be $A_g = (1.8 \pm 2.6) \cdot10^{-4}$. [...]

Rapidity correlations in inclusive two-particle production at storage ring energies / Dibon, Heinz ; Flügge, G ; Gottfried, Christian ; Nefkens, B M K ; Neuhofer, G ; Niebergall, F ; Regler, Meinhard ; Schmidt-Parzefall, W ; Schubert, K R ; Schumacher, P E et al.
Inclusive two-particle production in the reaction pp to gamma +ch+ (anything) has been measured at the CERN ISR for four energies ( square root s=23, 30.5, 45, and 53 GeV) at two production angles of the charged particles (ch) and at eight production angles of the gamma -rays. The rapidity correlation of the two particles is weak and of short range. [...]

Evidence for a change of slope in large-t elastic proton-proton scattering at square root s=53 GeV / De Kerret, H ; Aubert, Jean-Jacques ; Bartl, Walter ; Brandt, A ; Broll, C ; Büsser, F W ; Coignet, G ; Dibon, Heinz ; Eichinger, H ; Favier, Jean et al.
New experimental results are presented on proton-proton elastic scattering in the range of momentum transfer 4 GeV/sup 2/<-t<10 GeV /sup 2/ at the centre-of-mass energy of square root s=53 GeV. The data have been obtained using the split-field magnet detector at the CERN Intersecting Storage Rings. [...]
