Prospects for $K_{L} \to π^{0} ν ν ˉ$ , $K_{S} \to μ^{+} μ^{-}$ , $K_{L} \to π^{0} ℓ^{+} ℓ^{-}$ and $ε^{'} / ε$ after the new $K^{+} \to π^{+} ν ν ˉ$ result from NA62

Monika Blanke, Andrzej J. Buras, Cristina Lazzeroni +1

The recently announced NA62 measurement of the $K^{+} \to π^{+} ν ν ˉ$ branching ratio, based on 2016--2024 data, is fully consistent with its very accurate Standard Model (SM) predi…

Searches for hidden sectors using $K^{+} \to π^{+} X$ decays

NA62 Collaboration

Results from the study of the rare decays $K^{+} \to π^{+} ν ν ˉ$ , $K^{+} \to π^{+} μ^{+} μ^{-}$ and $K^{+} \to π^{+} γ γ$ at the NA62 experiment at CERN are interpreted in terms…

Search for heavy neutral leptons in $π^{+}$ decays to positrons

NA62 Collaboration

A search for heavy neutral lepton ( $N$ ) production in $π^{+} \to e^{+} N$ in-flight decays using data collected by the NA62 experiment at CERN in 2017-2024 is reported. Upper limits for…

Experimental Study of Rare Kaon Decays at J-PARC with KOTO and KOTO II

J. K. Ahn, E. Augustine, L. Bandiera +62

The rare kaon decay $K_{L} \to π^{0} ν ν ˉ$ is extremely sensitive to new physics, because the contribution to this decay in the Standard Model (SM) is highly suppressed and known very a…

Kaon Physics: A Cornerstone for Future Discoveries

Jason Aebischer, Atakan Tugberk Akmete, Riccardo Aliberti +153

The kaon physics programme, long heralded as a cutting-edge frontier by the European Strategy for Particle Physics, continues to stand at the intersection of discovery and innovati…

New bound on the vectorial axion-down-strange coupling from $K^{+} \to π^{+} ν ν ˉ$ data

Diego Guadagnoli, Axel Iohner, Cristina Lazzeroni +3

We reinterpret publicly available $K^{+} \to π^{+} ν ν ˉ$ data collected by NA62 from 2016 to 2024 to constrain the fundamental vectorial coupling of the QCD axion to down and strange…
