First detection of a tagged neutrino in the NA62 experiment

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 $K^{+}\to {\mu }^{+}{\nu }_{\mu }$ decay where the charged particles are reconstructed and the neutrino is detected through a charged-current interaction in a liquid krypton calorimeter.
