Observation of the K+π+νν¯ 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+π+νν¯ 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. [...]

The timing performance of the Timepix4 application-specific integrated circuit (ASIC) bump-bonded to a 100μm thick n-on-p silicon sensor is presented. A picosecond pulsed infrared laser was used to generate electron-hole pairs in the silicon bulk in a repeatable fashion, controlling the amount, position and time of the stimulated charge signal.

First search for K+π0πμe decays / NA62 Collaboration
The first search for the lepton number violating decay K+π0πμ+e+ and lepton flavour violating decays K+π0π+μe+, K+π0π+μ+e has been performed using a dataset collected by the NA62 experiment at CERN in 2016–2018. Upper limits of 2.9×1010, 3.1×1010 and 5.0×1010, 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 1.4×1017 protons on dump collected in 2021. No evidence for a dark photon signal is observed. [...]

First observation and study of the K±π0π0μ±ν decay / NA48/2 Collaboration
The NA48/2 experiment at CERN reports the first observation of the K±π0π0μ±ν decay based on a sample of 2437 candidates with 15% background contamination collected in 2003-2004. The decay branching ratio in the kinematic region of the squared dilepton mass above 0.03~GeV2/c4 is measured to be (0.65±0.03)×106. [...]

Measurement of the K+π+γγ decay / NA62 Collaboration
A sample of 3984 candidates of the K+π+γγ decay, with an estimated background of 291±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. [...]

Measurement of the very rare K+π+νν¯ decay / NA62 Collaboration
The decay K+π+νν¯, with a very precisely predicted branching ratio of less than 1010, is among the best processes to reveal indirect effects of new physics. The NA62 experiment at CERN SPS is designed to study the K+π+νν¯ decay and to measure its branching ratio using a decay-in-flight technique. NA62 took data in 2016, 2017 and 2018, reaching the sensitivity of the Standard Model for the K+π+νν¯ decay by the analysis of the 2016 and 2017 data, and providing the most precise measurement of the branching ratio to date by the analysis of the 2018 data. This measurement is also used to set limits on BR(K+π+X), where X is a scalar or pseudo-scalar particle. The final result of the BR(K+π+νν¯) measurement and its interpretation in terms of the K+π+X decay from the analysis of the full 2016-2018 data set is presented, and future plans and prospects are reviewed..
