DOI: 10.1007/jhep06(2025)189
Abstract: We present strategies for the Mu3e experiment to search for light, weakly coupled particles produced in rare muon decays, focusing on displaced e+e− decays within the hollow target. In most scenarios the backgrounds can be… read more here.

DOI: 10.1103/physrevd.110.035029
Abstract: Heavy neutral leptons (HNLs) are motivated by attempts to explain neutrino masses and dark matter. If their masses are in the MeV to several GeV range, HNLs are light enough to be copiously produced at collider… read more here.
