The international neutrino physics community has come together to develop the Deep Underground Neutrino Experiment (DUNE), a leading-edge experiment for neutrino science and proton decay studies. This experiment, together with the facility that will support it, the Long-Baseline Neutrino Facility (LBNF), will be an internationally designed, coordinated and funded program, hosted at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois.

DUNE represents the convergence of several formerly independent worldwide efforts around the opportunity provided by the megawatt neutrino beam facility planned at Fermilab and by the new significant expansion at the Sanford Underground Research Facility (Sanford Lab). DUNE will develop detectors to install at both sites, a fine-grained near neutrino detector to be installed 600 m downstream of the Fermilab beamline, and a 40,000 metric ton cryogenic liquid argon detector deployed deep underground at Sanford Lab, located 800 miles (1,300 km) downstream in Lead, South Dakota.

The DUNE experiment is expected to achieve transformative discoveries about neutrinos, making definitive determinations of neutrino properties,  the dynamics of the supernovae that produced the heavy elements necessary for life, and the possibility  of proton decay. The 1,300 km separation between the neutrino source and the far detector is optimal for the symmetry violation studies planned for DUNE and measuring other neutrino properties that may shed light on the origins of the universe.
