Description

Type I seesaw models generating small masses for the observed neutrinos predict not only heavy neutrinos but also the presence of lepton number violating (LNV) processes. After the discovery of these heavy neutrinos, it becomes essential to examine the amount of LNV in order to shed light on the corresponding neutrino mass-generating mechanism. We discuss the potential of future lepton colliders to not only discover LNV but also measure its size. Additionally, we comment on simple benchmark models able to capture the relevant physics with a minimal set of parameters.
