Description

The MicroBooNE experiment is an 85-tonne liquid argon time-projection chamber (LArTPC) that operated at Fermilab from 2015 to 2021, exposed to both the Booster Neutrino Beamline (BNB) and the Main Injector Neutrino Beamline (NuMI). Uniquely positioned, MicroBooNE sits off-axis to the NuMI beam and upstream of the NuMI hadron absorber, providing strong sensitivity to heavy, long-lived beyond-the-Standard-Model particles produced in meson decays. I will present our latest search for Heavy Neutral Leptons, and will show how new analysis techniques including high-precision timing and improved event reconstruction are allowing us to maximise the sensitivities from our full dataset.
