We present a phenomenological study of MicroBooNE’s ability to investigate $e^+e^-$ final states produced in dark photon mediated neutrino-upscattering—a beyond-Standard Model process proposed as a solution to the MiniBooNE anomaly. Utilising the similarities shared between the observable signatures of neutrino-induced $e^+e^-$ and single photons originating in the radiative decays of the $\Delta(1232)$ resonance, we consider MicroBooNE’s recent public data from its search for neutral current$\Delta(1232)$ radiative decays to test benchmark models of $e^+e^-$ production, and investigate MicroBooNE’s sensitivity to heavy neutrino models in which the neutrino sector is strongly coupled to a dark sector.
