This talk presents the most recent results from the MicroBooNE experiment, a neutrino detector that operated as part of Fermilab’s Short Baseline Neutrino (SBN) program. The primary motivation for the MicroBooNE experiment is to investigate the low-energy electron neutrino excess (LEE) that had previously been observed by LSND and MiniBooNE. For this purpose, MicroBooNE observed the interactions of neutrinos that were produced by the Booster Neutrino Beam (BNB) at a peak energy of ~700 MeV at a baseline of 470 m. The liquid argon time projection chamber technology of MicroBooNE provides fine-grained particle identification and an excellent energy resolution and thereby allows the experiment to test a number of proposed explanations for the LEE. This talk shows the results of the first LEE search that includes MicroBooNE’s entire data-taking period between 2015 and 2020 and gives an outlook on other upcoming analyses.
