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…

Searches for hidden sectors using $K^{+} \to I ¨ ^{+} X$ decays

NA62 Collaboration

Results from the study of the rare decays $K^{+} \to I ¨ ^{+} I^½ I^ˉ ½$ , $K^{+} \to I ¨ ^{+} I^¼^{+} I^¼^{-}$ and $K^{+} \to I ¨ ^{+} I^^{3} I^^{3}$ at the NA62 experiment at CERN are interpreted…

Testing T2K's Bayesian constraints with priors in alternate parameterisations

The T2K Collaboration, K. Abe, S. Abe +400

Bayesian analysis results require a choice of prior distribution. In long-baseline neutrino oscillation physics, the usual parameterisation of the mixing matrix induces a prior tha…

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…
