NO LESS: Novel Opportunities for Light Exotic Searches at the SPS
Babette Döbrich, Jan Jerhot, Karim Massri +2
A powerful way to test models with feebly interacting particles in the MeV to GeV mass range is through proton beam-dump experiments. In this paper, we compare the current sensitiv…
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 fo…
Feebly Interacting Particles: FIPs at LHCb
J. Alimena, J. Boyd, G. Cacciapaglia +36
With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader part…
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…
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 μ^…
