An international mega-science project

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.

Aiming for transformative discoveries about the universe

The DUNE experiment is designed to achieve discoveries that could transform our understanding of the origins and evolution of the universe:

  • Do neutrinos exhibit matter-antimatter asymmetries? Answering this question will help unravel the mystery of why matter generation dominated that of antimatter in the early universe.
  • DUNE’s observation of thousands of neutrinos from a core-collapse supernova in the Milky Way would allow us to peer inside a newly-formed neutron star and potentially witness the birth of a black hole.
  • With the world’s largest cryogenic particle detector deep underground, DUNE will be able to observe proton decay, if it should occur, and seek a relation between the stability of matter and the Grand Unification of forces.


A dual-site long-baseline facility

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.
