Let the Light Shine at DUNE - Prospects of Independent CPV Measurements and Low Energy Physics

• Wei Shi (Stony Brook University (US))

Room: Graduate Building D-122 Two of the most outstanding open questions in neutrino oscillation are the mass ordering and whether the CP is violated. Current generation experiments like T2K and NOvA are statistics limited when answering these questions. The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline neutrino oscillation experiment that’s being built in the US to solve these problems. It is designed with four far detector modules, each holding 17 kilotons of liquid argon. DUNE envisions a two-phased approach to achieve main physics goals and is ramping up its Phase II program that is fully endorsed by the 2023 P5. In this talk, I will discuss the importance of independent CP measurements and prospects offered by an enhanced light detection system at the Phase II FD. The same light detection system also boosts the low energy physics program. I will also introduce ongoing efforts to realize these prospects from the light detection side, including xenon doping and neutron tagging for Phase I FD, and enhanced light detection system prototyping for Phase II FD3.
