Recent results of the MicroBooNE experiment

Abstract

The MicroBooNE detector is the world's longest-running liquid argon time projection chamber (LArTPC), recording neutrinos from both the Booster Neutrino Beam (BNB) and the Neutrinos at the Main Injector beam (NuMI) at Fermilab. The MicroBooNE collaboration recently released a series of measurements aimed at investigating the nature of the excess of low-energy electromagnetic shower events observed by the MiniBooNE collaboration. In this talk, we will present the latest results from a series of three independent analyses looking for an anomalous excess of electron neutrino events, as well as a search for excessive single photons from neutrino-induced resonant decays. We additionally will highlight new results that use the well-understood selections to perform a search for an eV scale sterile neutrino in the full 3+1 oscillation framework. As part of the enriched physics topics of MicroBooNE, several recent cross-section measurements of neutrino-argon scattering and new physics searches will also be presented.

*The MicroBooNE work was done using the resources of the Fermi National Accelerator Laboratory (Fermilab), a U.S. Department of Energy, Office of Science, HEP User Facility. Fermilab is managed by Fermi Research Alliance, LLC (FRA), acting under Contract No. DE-AC02-07CH11359. MicroBooNE is supported by the following: the U.S. Department of Energy, Office of Science, Offices of High Energy Physics and Nuclear Physics; the U.S. National Science Foundation; the Swiss National Science Foundation; the Science and Technology Facilities Council (STFC), part of the United Kingdom Research and Innovation; the Royal Society (United Kingdom); and the UK Research and Innovation (UKRI) Future Leaders Fellowship. Additional support for the laser calibration system and cosmic ray tagger was provided by the Albert Einstein Center for Fundamental Physics, Bern, Switzerland. We also acknowledge the contributions of technical and scientific staff to the design, construction, and operation of the MicroBoo
