Search for Neutrino-Induced Neutral Current Δ Radiative Decay in MicroBooNE and a First Test of the MiniBooNE Low Energy Excess Under a Single-Photon Hypothesis

We report results from a search for neutrino-induced neutral current (NC) resonant \Delta(1232) baryon production followed by \Delta radiative decay, with a \langle0.8\rangle~GeV neutrino beam. Data corresponding to MicroBooNE's first three years of operations (6.80\times10^{20} protons on target) are used to select single-photon events with one or zero protons and... Show more
