Searches for hidden sectors using decays
NA62 Collaboration
Results from the study of the rare decays , and at the NA62 experiment at CERN are interpreted in terms…
Search for heavy neutral leptons in decays to positrons
NA62 Collaboration
A search for heavy neutral lepton () production in in-flight decays using data collected by the NA62 experiment at CERN in 2017-2024 is reported. Upper limits for…
Searching for Light Dark Matter and Dark Sectors with the NA64 experiment at the CERN SPS
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +49
Since its approval in 2016, NA64 has pioneered light dark matter (LDM) searches with electron, positron, muon, and hadron beams. The experiment has successfully met its primary obj…
High efficiency veto hadron calorimeter in the NA64 experiment at CERN
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +53
NA64 is a fixed-target experiment at the CERN SPS designed to search for Light particle Dark Matter (LDM) candidates with masses in the sub-GeV range. During the 2016-2022 runs, th…
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…
Proof of principle for a light dark matter search with low-energy positron beams at NA64
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +54
Thermal light dark matter (LDM) with particle masses in the 1 MeV - 1 GeV range could successfully explain the observed dark matter abundance as a relic from the primordial Univers…
