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. [...]

A search for the $K^+ \to \mu^- \nu e^+ e^+$ decay / NA62 Collaboration
A search for the $K^+ \to \mu^- \nu e^+ e^+$ decay forbidden within the Standard Model by either lepton number or lepton flavour conservation depending on the flavour of the emitted neutrino, has been performed using the dataset collected by the NA62 experiment at CERN in 2016–2018. An upper limit of $8.1 \times 10^{-11}$ is obtained for the decay branching fraction at 90% CL, improving by a factor of 250 over the previous search..

An investigation of the very rare $K^+\rightarrow\pi^+\nu\bar{\nu}$ decay / NA62 Collaboration
The NA62 experiment reports an investigation of the $K^+\rightarrow\pi^+\nu\bar{\nu}$ mode from a sample of $K^+$ decays collected in 2017 at the CERN SPS. The experiment has achieved a single event sensitivity of $(0.389\pm 0.024)\times10^{-10}$, corresponding to 2.2 events assuming the Standard Model branching ratio of $(8.4\pm1.0)\times10^{-11}$.

The NA62 first level trigger / Soldi, D (INFN, Turin ; Turin U.) ; Chiozzi, S (Ferrara U. ; INFN, Ferrara) ; Gamberini, E (CERN) ; Gianoli, A (Ferrara U. ; INFN, Ferrara) ; Mila, G (Ferrara U. ; INFN, Ferrara) ; Petrucci, F (Ferrara U. ; INFN, Ferrara) ; Neri, I (Ferrara U. ; INFN, Ferrara)
The NA62 experiment is designed to measure the ultra-rare decay $K^+→\pi ^{+}v\bar{v}$ branching ratio. The Standard Model prediction requires an extremebeam intensity to make the measurement. [...]

The NA62 LAV front-end electronics / Antonelli, A. (Frascati) ; Corradi, G. (Frascati) ; Moulson, M. (Frascati) ; Paglia, C. (Frascati) ; Raggi, M. (Frascati) ; Spadaro, T. (Frascati) ; Tagnani, D. (Frascati) ; Ambrosino, F. (Naples U.) ; Di Filippo, D. (Naples U.) ; Massarotti, P. (Naples U.) et al.
The branching ratio for the decay $K^+ \to \pi^+\nu\bar{\nu}$ is sensitive to new physics; the NA62 experiment will measure it to within about 10%. To reject the dominant background from channels with final state photons, the large-angle vetoes (LAVs) must detect particles with better than 1 ns time resolution and 10% energy resolution over a very large energy range.

Searches for lepton number violating $K^+$ decays / NA62 Collaboration
The NA62 experiment at CERN reports a search for the lepton number violating decays  $K^+ \to \pi^- e^+ e^+$ and $K^+ \to \pi^- \mu^+ \mu^+$ using a data sample collected in 2017. No signals are observed, and upper limits on the branching fractions of these decays of $2.2\times 10^{-10}$ and $4.2\times 10^{-11}$ are obtained, respectively, at 90\% confidence level. [...]
