Systematic Studies in the Single Photon Analysis of the MicroBooNE Experiment

The MicroBooNE detector was built with the investigation of the “low energy excess” (LEE) of electron neutrino and antineutrino charged current quasi-elastic events observed in the MiniBooNE experiment as one of its primary physics goals. One of the possible interpretations of the MiniBooNE LEE is that it is made up of neutrino-induced single-photon events. An analysis effort is underway at MicroBooNE to test this hypothesis via study of neutral current resonant delta production with subsequent radiative decay. This talk will cover the studies underway to fully understand the systematic uncertainties of this single photon analysis, including re-weighting Monte Carlo events to estimate the effect of many flux and cross-section uncertainties and the testing of the impact of detector simulation on the analysis results.
