Abstract

MicroBooNE is an 85-tonne active mass liquid argon time projection chamber at Fermilab. It has excellent calorimetric, spatial, and energy resolution, which makes it a powerful detector for neutrino and beyond the standard model (BSM) physics. One of the main physics goals of MicroBooNE is to investigate the nature of the excess of low-energy electromagnetic interactions observed by the MiniBooNE collaboration. In this seminar, I will present the latest results from a number of searches covering two leading hypotheses for the nature of the excess: an excess of single photons and an anomalous excess of electron neutrino events. I will provide details of these recent results and cross-checks to demonstrate the robustness of the analyses, and discuss both their interpretation and future studies in the wider context of the various BSM explanations of the MiniBooNE excess.
