Sterile Neutrino Search At MicroBooNE Using Both The BNB And NuMI Beams

MicroBooNE is an 85 tonne active volume liquid argon time projection chamber which detects neutrinos both on-axis from the Booster Neutrino Beam (BNB) and off-axis from the Neutrinos at the Main Injector (NuMI) beam. In this talk, I will describe a search for short baseline oscillations in a 3+1 sterile neutrino model, and compare our results with the LSND, Neutrino-4, and gallium anomalies. This search utilizes high performance charged current electron neutrino (ν_e) and muon neutrino (ν_μ) selections as well as a neutral current π⁰ selection. We describe the impact of a degeneracy caused by cancellation of ν_e appearance and disappearance, and demonstrate that this degeneracy can be broken by combining results from the BNB and NuMI beams which have substantially different ν_e/ν_μ ratios.
