Systematic Studies in the Gamma Low Energy Excess Analysis of the MicroBooNE Experiment

Not scheduled


Mr Gray Yarbrough (University of Tennessee Knoxville)


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. MicroBooNE is testing this hypothesis via a study of neutral current resonant delta production with subsequent radiative decay. This talk will cover the related studies 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. The analysis has secondary signal studies including neutral current pion production and subsequent decay which are used to constrain our final measurements. Simulations of this constraint predicting the impact on the data analysis will also be shown.


We simulate the impact of systematics on various gamma processes in the MicroBooNe detector.
