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…

Measurement of the $K^{+} \to π^{+} γ γ$ decay

The NA62 Collaboration

A sample of 3984 candidates of the $K^{+} \to π^{+} γ γ$ decay, with an estimated background of $291 \pm 14$ events, was collected by the NA62 experiment at CERN during 2017-2018. In order t…

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…

Search for $K^{+}$ decays to a muon and invisible particles

NA62 collaboration

The NA62 experiment at CERN reports searches for $K^{+} \to μ^{+} N$ and $K^{+} \to μ^{+} ν X$ decays, where $N$ and $X$ are massive invisible particles, using the 2016-2018 data set. The $N$ par…

Search for $π^{0}$ decays to invisible particles

NA62 Collaboration

The NA62 experiment at the CERN SPS reports a study of a sample of $4 \times 1 0^{9}$ tagged $π^{0}$ mesons from $K^{+} \to π^{+} π^{0} (γ)$ , searching for the decay of the $π^{0}$ to invisibl…

Measurement of ISR-FSR interference in the processes e+ e- --> mu+ mu- gamma and e+ e- --> pi+ pi- gamma

BABAR Collaboration

Charge asymmetry in processes e+ e- --> mu+ mu- gamma and e+ e- --> pi+ pi- gamma is measured using 232 fb-1 of data collected with the BABAR detector at center-of-mass energies ne…
