The origin of the light neutrino masses and the baryon asymmetry of the Universe are among the most significant unresolved issues in particle physics. One exciting solution is to extend the standard model with Heavy Neutral Leptons (HNLs), which can generate light neutrino masses via the type-I seesaw mechanism and the baryon asymmetry of the Universe through leptogenesis. HNLs with masses at or below the TeV scale can be probed experimentally through both direct and indirect searches. This talk will explore how the seesaw mechanism and leptogenesis can limit the properties of HNLs and the various experimental signatures that follow.
