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…

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…

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, i…

Proposal of the KOTO II experiment

Jung Keun Ahn, Antonella Antonelli, Giuseppina Anzivino +79

The KOTO II experiment is proposed to measure the branching ratio of the decay $K_{L} \to π^{0} ν ν ˉ$ at J-PARC. With a beamline to extract long-lived neutral kaons at 5 degrees from a…
