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 Î¼^…

Observation of the $K^{+} \to I ¨ ^{+} I^½ I^ˉ ½$ decay and measurement of its branching ratio

NA62 Collaboration

A measurement of the $K^{+} \to I ¨ ^{+} I^½ I^ˉ ½$ decay by the NA62 experiment at the CERN SPS is presented, using data collected in 2021 and 2022. This dataset was recorded, a…
