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…
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…
Experimental Study of Rare Kaon Decays at J-PARC with KOTO and KOTO II
J. K. Ahn, E. Augustine, L. Bandiera +62
The rare kaon decay is extremely sensitive to new physics, because the contribution to this decay in the Standard Model (SM) is highly suppressed and known ver…
Kaon Physics: A Cornerstone for Future Discoveries
Jason Aebischer, Atakan Tugberk Akmete, Riccardo Aliberti +153
The kaon physics programme, long heralded as a cutting-edge frontier by the European Strategy for Particle Physics, continues to stand at the intersection of discovery and innovati…
