Estimation of the thermal radiation induced desorption yield for hydrogen and helium at liquid helium temperatures / Jenninger, Berthold (CERN) ; Bez, Elena (CERN) ; Stöltzel, Anke (CERN) ; Rooijakkers, Fleur (CERN) ; Tiirinen, Eino (CERN)
Infrared radiation induced desorption of adsorbed molecules from cryogenic surfaces can lead to potentially detrimental pressure limitation in cryogenic UHV/XHV systems. For a sub-monolayer coverage, we determined the corresponding yields for hydrogen and helium exposed to room temperature radiation to be in the order of 1·10−4 and 0.02 m2(W·s)−1 respectively. [...]

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. [...]

Cylindrical hot cathode ionisation gauge – Construction and testing / Silva, Ricardo A S (Nova U., Lisboa) ; Bundaleski, Nenad (Nova U., Lisboa) ; Jenninger, Berthold (CERN) ; Teodoro, Orlando M N D (Nova U., Lisboa)
Hot cathode ionisation gauges are indispensable in measuring high and ultra-high vacuum. In the present work the construction details and the metrological evaluation of a novel gauge design — the cylindrical ionisation gauge is presented. [...]

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. [...]
