Status of searches for rare kaon decays at NA62 & HIKE / NA62 Collaboration
Recent results from searches for rare kaon decays with the NA62 experiment at CERN are reported, together with the future prospects. A future experiment HIKE, to go beyond NA62, has been proposed to push kaon physics to an unprecedented frontier [...]

Experimental Study of Rare Kaon Decays at J-PARC with KOTO and KOTO II / KOTO Collaboration
The rare kaon decay $K_L\to\pi^0\nu\bar{\nu}$ is extremely sensitive to new physics, because the contribution to this decay in the Standard Model (SM) is highly suppressed and known very accurately; the branching ratio is $3\times 10^{-11}$ in the SM with a theoretical uncertainty of just 2%. [...]

Recent results from the NA62 experiment at CERN / NA62 Collaboration
The NA62 experiment at CERN SPS is designed to study the $K^+\to\pi^+\nu\bar\nu$ decay. After collecting data in 2016, 2017, and 2018, the experiment has resumed data taking in 2021 and has received approval for operations until the onset of LS3. [...]

FCC-ee positron source from conventional to crystal-based / Alharthi, Fahad (KACST, Riyadh ; IJCLab, Orsay) ; Chaikovska, Iryna (IJCLab, Orsay) ; Chehab, Robert (IJCLab, Orsay) ; Mytrochenko, Viktor (IJCLab, Orsay) ; Wang, Yuting (IJCLab, Orsay) ; Zhao, Yongke (CERN) ; Bandiera, Laura (INFN, Ferrara) ; Canale, Nicola (INFN, Ferrara) ; Guidi, Vincenzo (INFN, Ferrara ; Ferrara U.) ; Malagutti, Lorenzo (INFN, Ferrara) et al.
The high-luminosity requirement in future lepton colliders imposes a need for a high-intensity positron source. In the conventional scheme, positron beams are obtained by the conversion of bremsstrahlung photons into electron-positron pairs through the interaction between a high-energy electron beam and a high-Z amorphous target.

Physics Beyond the Standard Model with the NA62 experiment at CERN / NA62 Collaboration
The first measurement of the branching ratio of the ultra-rare $K^+ \to \pi^+\nu\bar\nu$ decay and the searches for production of feebly interacting particles predicted by dark scalar models from the NA62 experiment at CERN are presented. The results of a search for in-flight decays of dark photon to $\ell^+\ell^-$ pairs with data collected in beam-dump mode in 2021 are also reported..

Search for hadronic decays of feebly-interacting particles at NA62 / NA62 Collaboration
The NA62 experiment at CERN has the capability to collect data in a beam-dump mode, where 400 GeV protons are dumped on an absorber. In this configuration, New Physics particles, including dark photons, dark scalars, and axion-like particles, may be produced in the absorber and decay in the instrumented volume beginning approximately 80 m downstream of the dump.

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) ; Numao, Toshio (TRIUMF) ; Velghe, Bob (TRIUMF) ; Wong, Vincent Wai Sum (TRIUMF) ; Bryman, Douglas (British Columbia U. ; 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 detection of a tagged neutrino in the NA62 experiment / NA62 Collaboration
The NA62 experiment at the CERN SPS reports the first detection of a tagged neutrino candidate based on the data collected in 2022. The candidate consists of a $K^+ \rightarrow \mu^+ \nu_{\mu}$ decay where the charged particles are reconstructed and the neutrino is detected through a charged-current interaction in a liquid krypton calorimeter..
