Summary

Outline

  1. Neutrino oscillation can address fundamental questions.
    • Determine ordering of mass states
    • Measure CP symmetry violation phase
  2. They need to reconstruct their incident neutrino energy event by event.
  3. Nuclear physics makes this hard.
  4. We tested this with electrons.
  5. There are serious discrepancies.
