Gaia Data Release 3 - Stellar multiplicity, a teaser for the hidden treasure / Gaia Collaboration
Context.TheGaiaDR3 catalogue contains, for the first time, about 800 000 solutions with either orbital elements or trend parameters for astrometric, spectroscopic, and eclipsing binaries, and combinations of these three.Aims.With this paper, we aim to illustrate the huge potential of this large non-single-star catalogue.Methods.Using the orbital solutions and models of the binaries, we have built a catalogue of tens of thousands of stellar masses or lower limits thereof, some with consistent flux ratios. Properties concerning the completeness of the binary catalogues are discussed, statistical features of the orbital elements are explained, and a comparison with other catalogues is performed.Results.Illustrative applications are proposed for binaries across the Hertzsprung-Russell Diagram (HRD).

Observation of the $K^+ \to \pi^+ \nu \bar\nu$ decay and measurement of its branching ratio / Cortina Gil, Eduardo (Louvain U., CP3) ; Jerhot, Jan (Louvain U., CP3 ; Munich, Max Planck Inst.) ; Lurkin, Nicolas (Louvain U., CP3) ; Bryman, Douglas (British Columbia U. ; TRIUMF) ; Numao, Toshio (TRIUMF) ; Velghe, Bob (TRIUMF) ; Wong, Vincent Wai Sum (TRIUMF) ; Hives, Zdenko (Charles U.) ; Husek, Tomas (Charles U. ; Birmingham U.) ; Kampf, Karol (Charles U.) et al.
A measurement of the $K^+ \to \pi^+ \nu \bar\nu$ decay by the NA62 experiment at the CERN SPS is presented, using data collected in 2021 and 2022. This dataset was recorded, after modifications to the beamline and detectors, at a higher instantaneous beam intensity with respect to the 2016–2018 data taking. [...]

First search for $K^+ \to \pi^0 \pi \mu e$ decays / NA62 Collaboration
The first search for the lepton number violating decay $K^+ \to \pi^0 \pi^- \mu^+ e^+$ and lepton flavour violating decays $K^+ \to \pi^0 \pi^+ \mu^- e^+$, $K^+ \to \pi^0 \pi^+ \mu^+ e^-$ has been performed using a dataset collected by the NA62 experiment at CERN in 2016–2018. Upper limits of $2.9\times 10^{-10}$, $3.1 \times 10^{-10}$ and $5.0 \times 10^{-10}$, respectively, are obtained at 90% CL for the branching ratios of the three decays on the assumption of uniform phase-space distributions..

Development of a new CEDAR for kaon identification at the NA62 experiment at CERN / NA62 Collaboration
The NA62 experiment at CERN utilises a differential Cherenkov counter with achromatic ring focus (CEDAR) for tagging kaons within an unseparated monochromatic beam of charged hadrons. The CEDAR-H detector was developed to minimise the amount of material in the path of the beam by using hydrogen gas as the radiator medium. [...]

Search for leptonic decays of dark photons at NA62Search for Leptonic Decays of Dark Photons at NA62 / NA62 Collaboration
The NA62 experiment at CERN, configured in beam-dump mode, has searched for dark photon decays in flight to electron-positron pairs using a sample of $1.4 \times 10^{17}$ protons on dump collected in 2021. No evidence for a dark photon signal is observed. [...]

Measurement of the $K^+ \to \pi^+ \gamma \gamma$ decay / NA62 Collaboration
A sample of 3984 candidates of the $K^+ \to \pi^+ \gamma \gamma$ decay, with an estimated background of $291 \pm 14$ events, was collected by the NA62 experiment at CERN during 2017–2018. In order to describe the observed di-photon mass spectrum, the next-to-leading order contribution in chiral perturbation theory was found to be necessary. [...]
