Beschreibung: <jats:title>Abstract</jats:title><jats:p>The sensitivity of the Deep Underground Neutrino Experiment (DUNE) to neutrino oscillation is determined, based on a full simulation, reconstruction, and event selection of the far detector and a full simulation and parameterized analysis of the near detector. Detailed uncertainties due to the flux prediction, neutrino interaction model, and detector effects are included. DUNE will resolve the neutrino mass ordering to a precision of 5<jats:inline-formula><jats:alternatives><jats:tex-math>$$\sigma $$</jats:tex-math><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>σ</mml:mi> </mml:math></jats:alternatives></jats:inline-formula>, for all <jats:inline-formula><jats:alternatives><jats:tex-math>$$\delta _{\mathrm{CP}}$$</jats:tex-math><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub> <mml:mi>δ</mml:mi> <mml:mi>CP</mml:mi> </mml:msub> </mml:math></jats:alternatives></jats:inline-formula> values, after 2 years of running with the nominal detector design and beam configuration.
