Christopher Marshall (LBNL) “The Dawn of DUNE: Neutrino Oscillations in the Precision Era”
March 24, 2020 @ 4:00 pm - 5:00 pm
ABSTRACT:
Neutrino oscillation is a well-established phenomenon. Over the past two decades, nearly all of the parameters governing these oscillations have been measured experimentally, using neutrinos from the atmosphere, the sun, nuclear reactors, and particle accelerators. The remaining unknowns have very interesting consequences but are challenging to access experimentally as they require high-precision measurements. The Deep Underground Neutrino Experiment (DUNE) will be sensitive to these unknowns, including whether neutrinos violate CP symmetry, which could be the key to understanding why the universe is matter-dominated. Constraining systematic uncertainties is critical for DUNE to reach its physics goals, and requires a highly-capable near detector. I will present the discovery potential of DUNE and discuss how the experiment is designed to address the many challenges of precision neutrino oscillation physics. I will give particular focus to how the near detector can mitigate large uncertainties on the neutrino flux prediction and interaction cross sections.
