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…

A study of the $K^{+} \to π^{0} e^{+} ν γ$ decay

The NA62 Collaboration

A sample of $1.3 \times 1 0^{5}$ $K^{+} \to π^{0} e^{+} ν γ$ candidates with less than 1% background was collected by the NA62 experiment at the CERN SPS in 2017-2018. Branching fraction mea…

A search for the $K^{+} \to μ^{-} ν e^{+} e^{+}$ decay

NA62 collaboration

A search for the $K^{+} \to μ^{-} ν e^{+} e^{+}$ decay, forbidden within the Standard Model by either lepton number or lepton flavour conservation depending on the flavour of the emitted neutri…

A measurement of the $K^{+} \to π^{+} μ^{+} μ^{-}$ decay

NA62 Collaboration

A sample of $2.8 \times 1 0^{4}$ $K^{+} \to π^{+} μ^{+} μ^{-}$ candidates with negligible background was collected by the NA62 experiment at the CERN SPS in 2017--2018. The model-inde…
