We present a novel single-photon detector based on a vacuum tube incorporating a photocathode, a microchannel plate (MCP), and a Timepix4 CMOS ASIC functioning as a pixelated anode. Designed to handle photon rates up to 1 billion per second across a $7$ $\text{cm}^2$ active area, the detector achieves outstanding spatial and temporal resolutions of $5 - 10$ $\mu\text{m}$ and below $50$ $\text{ps}$ r.m.s., respectively.

Abstract
The use of a new optoelectronic readout chain with
𝒪(100)ps time resolution is a major milestone in the
development of RICH detectors for environments with a high number of
particle interactions per bunch crossing, such as the
High-Luminosity LHC. A prototype chain, based on MAPMT and SiPM
photon sensors coupled to readout electronics integrating the FastIC
ASIC and a TDC-in-FPGA, is presented. [...]

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..

Timing resolution performance of Timepix4 bump-bonded assemblies
/ Bolzonella, R. (INFN, Ferrara) ; Alozy, J. (CERN) ; Ballabriga, R. (CERN) ; van Beuzekom, M. (NIKHEF, Amsterdam) ; Biesuz, N.V. (INFN, Ferrara) ; Campbell, M. (CERN) ; Cardarelli, P. (INFN, Ferrara) ; Cavallini, V. (INFN, Ferrara) ; Coco, V. (CERN) ; Cotta Ramusino, A. (INFN, Ferrara) et al.
The timing performance of the Timepix4 application-specific integrated circuit (ASIC) bump-bonded to a $100\;\mu\textrm{m}$ 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 $K^+ \to \pi^0 \pi \mu e$ 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. [...]
