Abstract
Lepton number violation (LNV) is usually searched for by the LHC collaborations using the same-sign dilepton plus jet signature. In this paper, we discuss multilepton signals of LNV that can arise with experimentally interesting rates in certain loop models of neutrino mass generation. Interestingly, in such models, the observed smallness of the active neutrino masses, together with the high multiplicity of the final states, leads in large parts of the viable parameter space of such models to the prediction of long-lived charged particles, which leave highly ionizing tracks in the detectors. We focus on one particular one-loop neutrino mass model in this class and discuss its LHC phenomenology in some detail.

Summary
Lepton number violation (LNV) is usually searched for by the LHC collaborations using the same-sign dilepton plus jet signature [1,2]. This signal was first proposed in the context of the left-right symmetric model [3], but appears—at least in principle—in all Majorana neutrino mass models.. This kind of exotic LNV signatures appears in specific loop models of neutrino mass generation. Radiative neutrino mass models have a long history [4,5,6,7]; see the recent review [8]
