In this document, we describe the wealth of science opportunities and
capabilities of LBNE, the Long-Baseline Neutrino Experiment. LBNE has been
developed to provide a unique and compelling program for the exploration of key questions at the forefront of particle physics. Chief among the discovery
opportunities are observation of CP symmetry violation in neutrino mixing,
resolution of the neutrino mass hierarchy, determination of maximal or
near-maximal mixing in neutrinos, searches for nucleon decay signatures, and
detailed studies of neutrino bursts from galactic supernovae. To fulfill these
and other goals as a world-class facility, LBNE is conceived around four
central components: (1) a new, intense wide-band neutrino source at Fermilab,
(2) a fine-grained `near' neutrino detector just downstream of the source, (3)
the Sanford Underground Research Facility (SURF) in Lead, South Dakota at an
optimal distance (~1300 km) from the neutrino source, and (4) a massive liquid
argon time-projection chamber (LArTPC) deployed there as a 'far' detector. The
facilities envisioned are expected to enable many other science opportunities
due to the high event rates and excellent detector resolution from beam
neutrinos in the near detector and atmospheric neutrinos in the far detector.
This is a mature, well developed, world class experiment whose relevance,
importance, and probability of unearthing critical and exciting physics has
increased with time.
