Z's in neutrino scattering at DUNE

Novel leptophilic neutral currents can be tested at upcoming neutrino oscillation experiments using two complementary processes, neutrino trident production and neutrino-electron (ν − e) elastic scattering. Considering generic anomaly-free Uð1Þ extensions of the Standard Model, we discuss the characteristics of ν − e scattering as well as eþe− and μþμ− trident production at the DUNE near detector in the presence of such beyond the Standard Model scenarios. We then determine the sensitivity of DUNE in constraining the well-known Le − Lμ and Lμ − Lτ models. We conclude that DUNE will be able to probe these leptophilic models with unprecedented sensitivity, covering unproved explanations of the ðg − 2Þμ discrepancy
