Precision measurements of neutrino-electron scattering may provide a viable way to test the non-minimal form of the charged and neutral current weak interactions within a hypothetical near-detector setup for the Deep Underground Neutrino Experiment (DUNE). Although low-statistics, these processes are clean and provide information complementing the results derived from oscillation studies. They...
Heavy neutral leptons (HNL) are among the hypothetical ingredients behind nonzero neutrino masses. If sufficiently light, they can be produced and detected in fixed-target-like experiments. We show that if the HNLs belong to a richer -- but rather generic -- dark sector, their production rate can deviate dramatically from expectations associated to the standard-model weak interactions. In this...
Symmetry protected type I seesaw models have been proposed as an explanation for the small masses of the observed neutrinos. These predict heavy neutral leptons that are organized in pseudo-Dirac pairs, whose mass splitting induces heavy neutrino-antineutrino oscillations. We employ a minimal phenomenological model to discuss the ability of future lepton collider experiments to probe the...
