Description
The Deep Underground Neutrino Experiment (DUNE) is a long-baseline accelerator neutrino experiment aiming to measure neutrino oscillations, most importantly, to determine whether violation of CP symmetry occurs in the leptonic sector. The Far Detector (FD) of DUNE will be constructed as four Liquid Argon Time Projection Chamber (LArTPC) modules with a total Liquid Argon mass of 70 kt. Thanks to the very high resolution spatial tracking of particles in LArTPC modules, the DUNE FD is expected to achieve excellent reconstruction of neutrino energy and zenith angle. The FD will be located 1500 m underground at the Sanford Underground Research Facility, South Dakota, with the large rock overburden drastically reducing cosmic muon backgrounds. Therefore, the DUNE FD will also function as an atmospheric neutrino experiment. In this contribution, we present a sensitivity study to Neutrino Mass Ordering and sterile neutrinos in the (3+1) flavor model. Using a simplified detector response parametrization and conservative assumptions on the detector performance, we show that atmospheric neutrino measurements with the DUNE FD will yield competitive sensitivities for an exposure of 400 kt-year.
