Lepton Number Violation: from $0\nu \beta \beta$ Decay to Long-Lived Particle Searches

Gang Li, Michael J. Ramsey-Musolf, Shufang Su +1

We study the complementary tests of lepton number violation in $0\nu \beta \beta$-decay experiments, long-lived particle (LLP) searches at the LHC main detectors ATLAS/CMS, and a proposed far…
