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…

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…
