Description
Neutrino oscillations have led to the discovery that neutrinos have nonzero masses. The current model describes the oscillation phenomenon in terms of three mixing angles and one CP-violating phase. Within the three-flavour paradigm, the other two major unknowns are the neutrino mass ordering and whether charge-parity is violated in the leptonic sector. The Deep Underground Neutrino Experiment (DUNE) is an ambitious research program in neutrino physics under construction at Fermilab and the Sanford Underground Research Facility (SURF), uniquely designed to measure many oscillation parameters and eventually test the validity of the oscillation model. Additionally, its design will offer the opportunity for non-beam related neutrino physics including supernova neutrinos, atmospheric neutrinos, and neutrinos originating in the core of the Sun. DUNE is a long baseline neutrino oscillation experiment with a detector close to the neutrino beam source at Fermilab (Near Detector) and a detector 1300 km away in South Dakota (Far Detector). Both the Near and Far Detector are based on Liquid Argon Time Projection Chamber (LArTPC) technology that measures neutrinos and antineutrinos over a wide range of energies. The Near Detector measures the unoscillated neutrino flux and constrains systematic uncertainties to predict the neutrino flux at the Far Detector, where the oscillated (anti-)neutrino beam is measured. The Far Detector will comprise at least two multi-kiloton underground LArTPCs, and the Near Detector will consist of a LArTPC module combined with two additional tracking detectors to obtain a robust characterization of the neutrino flux. In this talk, I will present the rich DUNE neutrino physics program, its sophisticated design, and the results from the Near and Far detector prototypes, together with the current status and future plans, emphasizing the contributions of the Canadian institutions involved.
