LBNE
General Information
The Long Baseline Neutrino Experiment (LBNE) is a proposed next-generation accelerator-driven neutrino experiment that will use a high power neutrino beam originating at Fermilab near Chicago. After travelling more than 1000 km through the earth the beam will be incident on the world’s largest underground detector under the Black Hills in South Dakota. The primary physics goals of LBNE is a measurement of the CP violating phase angle δ, which may help physicists understand the matter dominated nature of the universe. It is anticipated that the experiment will also resolve so-called “neutrino mass-hierarchy problem,” and make precise measurements of other parameters in the neutrino mass mixing matrix. The very large detector required for these measurements will also enable measurements in a broad range of additional areas of great interest to high energy physicists and astrophysicists including proton decay (which may cast light on Grand Unified Theories), supernova burst neutrino measurements and discovery of supernova “relic” neutrinos that are the remnants of the billions of supernovae that have occurred during the lifetime of the universe to date.
