This work focuses on lepton- and baryon-number-violating interactions in simplified models and effective field theory. Using both high- and low-scale observables, lepton number violation is constrained in dimension-7 operators and their tree-level UV-completions. Moreover, novel ways are proposed to disentangle the nature of neutrinos using rare kaon decays and coherent elastic neutrino-nucleus scattering. Finally, baryogenesis is studied in a model that induces baryon-number-violating neutron-antineutron oscillation.
