Search for heavy neutral leptons in $\pi^+$ decays to positrons / Bloch-Devaux, Brigitte (Louvain U., CP3 ; Birmingham U.) ; Cortina Gil, Eduardo (Louvain U., CP3) ; Minucci, Elisa (Louvain U., CP3 ; Frascati) ; Padolski, Sergey (Louvain U., CP3) ; Petrov, Plamen (Louvain U., CP3) ; Numao, Toshio (TRIUMF) ; Petrov, Yevgeniy (TRIUMF) ; Velghe, Bob (TRIUMF) ; Wong, Vincent Wai Sum (TRIUMF) ; Shang, Victor (TRIUMF) et al.
A search for heavy neutral lepton ($N$) production in $\pi^+\to e^+ N$ in-flight decays using data collected by the NA62 experiment at CERN in 2017-2024 is reported. Upper limits for the extended neutrino mixing matrix element $|U_{e4}|^2$ are established at the level of $10^{-8}$ for heavy neutral leptons with mass in the range 95-126 MeV/$c^2$ and lifetime exceeding 50 ns..

Searches for hidden sectors using $K^+\to\pi^+X$ decays / Cortina Gil, Eduardo (Louvain U., CP3) ; Jerhot, Jan (Louvain U., CP3 ; Munich, Max Planck Inst.) ; Minucci, Elisa (Louvain U., CP3 ; Frascati) ; Padolski, Sergey (Louvain U., CP3) ; Petrov, Plamen (Louvain U., CP3) ; Shaikhiev, Artur (Louvain U., CP3 ; Lancaster U.) ; Volpe, Roberta (Louvain U., CP3 ; INFN, Perugia) ; Numao, Toshio (TRIUMF) ; Petrov, Yevgeniy (TRIUMF) ; Velghe, Bob (TRIUMF) et al.
Results from the study of the rare decays $K^+\to\pi^+\nu\bar{\nu}$, $K^{+}\to \pi^{+}\mu^{+}\mu^{-}$ and $K^{+}\to\pi^{+}\gamma\gamma$ at the NA62 experiment at CERN are interpreted in terms of improved limits for $B(K^+\to\pi^+X)$ and coupling parameters of hidden-sector models, where X is a mediator. World-leading limits are achieved for dark photon, dark scalar and axion-like particle models..

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. [...]

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.

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..

Search for resonant pair production of Higgs bosons in the $ \textrm{b}\overline{\textrm{b}}\textrm{b}\overline{\textrm{b}} $ final state using large-area jets in proton-proton collisions at $ \sqrt{s} $ = 13 TeV / CMS Collaboration
A search is presented for the resonant production of a pair of standard model-like Higgs bosons using data from proton-proton collisions at a centre-of-mass energy of 13 TeV, collected by the CMS experiment at the CERN LHC in 2016-2018, corresponding to an integrated luminosity of 138 fb$ ^{-1} $. The final state consists of two b quark-antiquark pairs. [...]
