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…

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…

The upper limit on the $K^{+} \to π^{0} π^{0} π^{0} e^{+} ν$ decay

A. V. Kulik, S. N. Filippov, E. N. Gushchin +26

A search for the $K^{+} \to π^{0} π^{0} π^{0} e^{+} ν$ decay is performed by the OKA collaboration. The search is based on $3.65 \times 1 0^{9} K^{+}$ decays. No signal is observed. The upp…
