Probing Neutrino Compositeness with Invisible and Displaced Signals
Matteo Borrello, Marco Costa, Diego Redigolo +1
We explore the possibility that neutrinos couple to an interacting sterile sector, providing a novel portal that generalizes the heavy neutral lepton portal to a composite setting.…

Letter Of Intent for a future experiment at the High Intensity Muon Beam facility at PSI
Paolo Walter Cattaneo, Wataru Ootani, Francesco Renga +61
Searches for charged lepton flavor violation in the muon sector stand out among the most sensitive and clean probes for physics beyond the Standard Model. Currently, $μ^+ \to \math…

Displaced Searches for Axion-Like Particles and Heavy Neutral Leptons at Mu3e
Simon Knapen, Toby Opferkuch, Diego Redigolo +1
We present strategies for the Mu3e experiment to search for light, weakly coupled particles produced in rare muon decays, focusing on displaced decays within the hollow ta…
