MicroBooNE is a Liquid Argon Time Projection Chamber (LArTPC) neutrino experiment on the Booster Neutrino Beamline at the Fermi National Accelerator Laboratory, with an 85-tonne active mass.
One of MicroBooNE’s primary physics goals is to investigate the excess of electron neutrino events seen by MiniBooNE in the [200-600] MeV range.
MicroBooNE will constrain the intrinsic electron neutrino component of the beam by measuring the muon neutrino spectrum.
Our low-energy excess analysis makes use of deep learning algorithms applied to the high-resolution images provided by the MicroBooNE LAr

Neutrinos have played a key role in astrophysics, from the characterization of nuclear fusion processes in the Sun to the observation of supernova SN1987A and multiple extragalactic events. The Super-Kamiokande experiment has played a major part in past in these astrophysical studies by investigating low energy O(10)~MeV neutrinos, and currently exhibits the best sensitivity to the diffuse neutrino background from distant supernovae.

The KATRIN (Karlsruhe Tritium Neutrino) experiment investigates the energetic endpoint of the tritium beta-decay spectrum to determine the effective mass of the electron anti-neutrino. The collaboration reported its first neutrino mass result in fall 2019. Its unprecedented tritium source luminosity and spectroscopic quality make it a unique instrument to also search for physics beyond the standard model such as eV or keV sterile neutrinos.

Atmospheric neutrino experiments measure the oscillations of neutrinos produced in the atmosphere by default assuming unitary mixing of electron-, muon-, and tau-neutrinos. The task-list for the upcoming years involves: (a) Measure the atmospheric mixing parameters with increased precision. (b) Determine the known unknowns in the framework of three neutrino flavours: ordering of neutrino masses and CP-violation.
