Long-baseline Neutrino Oscillation Sensitivity with DUNE

The Deep Underground Neutrino Experiment (DUNE) is a next-generation experiment that will measure neutrino and antineutrino oscillations with a very long baseline in a wideband beam. DUNE will definitively resolve the neutrino mass ordering, and has discovery sensitivity to CP violation over a broad range of possible parameter values. A particular strength of DUNE is the ability to use spectral information to resolve degeneracies between parameters in the three-flavor model, and to test the validity of that model. Neutrino oscillation sensitivities will be presented, with a focus on DUNE's long-term precision measurement capability.
