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…

First detection of a tagged neutrino in the NA62 experiment

NA62 Collaboration

The NA62 experiment at the CERN SPS reports the first detection of a tagged neutrino candidate based on the data collected in 2022. The candidate consists of a $K^+ \rightarrow μ^+…

Development of a new CEDAR for kaon identification at the NA62 experiment at CERN

The NA62 Collaboration

The NA62 experiment at CERN utilises a differential Cherenkov counter with achromatic ring focus (CEDAR) for tagging kaons within an unseparated monochromatic beam of charged hadro…

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…
