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.

First observation and study of the $K^{\pm} \to \pi^{\pm} \pi^{0} e^{+} e^{-}$ decay / NA48/2 Collaboration
The NA48/2 experiment at CERN reports the first observation of the $K^\pm \to \pi^\pm \pi^0 e^+ e^-$ decay from an exposure of $1.7 \times 10^{11}$ charged kaon decays recorded in $2003-2004$. A sample of 4919 candidates with 4.9% background contamination allows the determination of the branching ratio in the full kinematic region, BR($K^\pm \to \pi^\pm \pi^0 e^+ e^-)=(4.24 \pm 0.14)\times10^{-6}$.

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. [...]

Search for the dark photon in $\pi^0$ decays / NA48/2 Collaboration
A sample of $1.69\times 10^7$ fully reconstructed $\pi^0\to\gamma e^+e^-$ decay candidates collected by the NA48/2 experiment at CERN in $2003-2004$ is analysed to search for the dark photon ($A'$) production in the $\pi^0\to\gamma A'$ decay followed by the prompt $A'\to e^+e^-$ decay. No signal is observed, and an exclusion region in the plane of the dark photon mass $m_{A'}$ and mixing parameter $\varepsilon^2$ is established. [...]

Muon Energy Estimate Through Multiple Scattering with the Macro Detector / MACRO Collaboration
Muon energy measurement represents an important issue for any experiment addressing neutrino induced upgoing muon studies. Since the neutrino oscillation probability depends on the neutrino energy, a measurement of the muon energy adds an important piece of information concerning the neutrino system. [...]

The beam and detector of the NA62 experiment at CERN / NA62 Collaboration
NA62 is a fixed-target experiment at the CERN SPS dedicated to measurements of rare kaon decays. Such measurements, like the branching fraction of the $K^{+} \rightarrow \pi^{+} \nu \bar\nu$ decay, have the potential to bring significant insights into new physics processes when comparison is made with precise theoretical predictions.
