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. [...]

Review of particle physics / Particle Data Group Collaboration
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,717 new measurements from 869 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons [...]

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..

Kaon physics is at a turning point -- while the rare-kaon experiments NA62 and KOTO are in full swing, the end of their lifetime is approaching and the future experimental landscape needs to be defined. With HIKE, KOTO-II and LHCb-Phase-II on the table and under scrutiny, it is a very good moment in time to take stock and contemplate about the opportunities these experiments and theoretical developments provide for particle physics in the coming decade and beyond.

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. [...]

SHADOWS Technical Proposal / SHADOWS Collaboration
We propose a new proton beam-dump experiment, SHADOWS, to search for a large variety of feebly-interacting particles possibly produced in the interactions of a 400 GeV proton beam with a copper-iron based dump. [...]

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. [...]
