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

NA62 Collaboration

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

Search for Leptonic Decays of Dark Photons at NA62

The NA62 collaboration

The NA62 experiment at CERN, configured in beam-dump mode, has searched for dark photon decays in flight to electron-positron pairs using a sample of $1.4 \times 1 0^{17}$ protons on…
