Title: Searches for long-lived heavy neutrinos at colliders

Abstract: Many scenarios of new physics predict the production of long-lived particles, which decay at a visible distance from their production point. One example is that of heavy neutrinos, whose discovery could help explain neutrino oscillations, dark matter, and the baryon asymmetry. The displaced-vertex signature of such a particle provides a powerful background-suppression handle. It also presents unique challenges that originate from the design of the detector and reconstruction software. I will discuss these aspects mainly through our recent ATLAS search (arXiv:1905.09787) and a proposed search for such a particle at B factories (arXiv:1908.09719).
