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 $(0.65 \pm 0.03) \times 10^{-6}$. [...]

Precision measurement of the form factors of semileptonic charged kaon decays from NA48/2 / NA48/2 Collaboration
We present a measurement of the charged kaon semileptonic form factors based on 4.3 million $K^± → π^0 e^± \nu_e$ and 2.9 million $K^± → π^0 μ^± \nu_μ$ decays collectedby the NA48/2 experiment. The single results for the semi-electronic and semi-muonic channel have better and similar precision, respectively, than previousmeasurements. [...]

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. [...]

A sample of almost 2000 $K^\pm \to \pi^\pm \pi^0 e^+ e^-$ rare decays with a background contamination below 3% is observed for the first time by the NA48/2 experiment at CERN/SPS. The preliminary branching ratio in the full kinematic region is obtained to be $BR(K^\pm \to \pi^\pm \pi^0 e^+ e^-)$ = (4.06 ± 0.17) x $10^{-6}$ by analyzing the data set recorded in 3-month NA48/2 run during 2003.

Searches for lepton number violation and resonances in $K^{\pm} \rightarrow \pi\mu\mu$ decays / NA48/2 Collaboration
The NA48/2 experiment at CERN collected a large sample of charged kaon decays to final states with multiple charged particles in 2003--2004. A new upper limit on the rate of the lepton number violating decay $K^{\pm}\to\pi^{\mp}\mu^{\pm}\mu^{\pm}$ is reported: $\mathcal{B}(K^{\pm}\to\pi^{\mp}\mu^{\pm}\mu^{\pm})<8.6 \times 10^{-11}$ at 90% CL.
