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…

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…

Using graph neural networks to reconstruct charged pion showers in the CMS High Granularity Calorimeter

M. Aamir, G. Adamov, T. Adams +568

A novel method to reconstruct the energy of hadronic showers in the CMS High Granularity Calorimeter (HGCAL) is presented. The HGCAL is a sampling calorimeter with very fine transv…
