Long-baseline neutrino oscillation physics potential of the DUNE experiment


The sensitivity of the Deep Underground Neu trino Experiment (DUNE) to neutrino oscillation is deter mined, based on a full simulation, reconstruction, and event selection of the far detector and a full simulation and param eterized analysis of the near detector. Detailed uncertain ties due to the flux prediction, neutrino interaction model, and detector effects are included. DUNE will resolve the neutrino mass ordering to a precision of 5σ, for all δCP values, after 2 years of running with the nominal detec tor design and beam configuration. It has the potential to observe charge-parity violation in the neutrino sector to a precision of 3σ (5σ) after an exposure of 5 (10) years, for 50% of all δCP values. It will also make precise mea surements of other parameters governing long-baseline neu trino oscillation, and after an exposure of 15 years will achieve a similar sensitivity to sin2 2θ13 to current reactor experiments.
