Description
The "Supernova physics at DUNE" workshop will be held from the morning of March 11th, 2016, until the early afternoon of March 12th, 2016, at Virginia Tech (Blacksburg campus).

Recent advances in the LBNF/DUNE effort have brought new focus on low-energy neutrino physics. The objectives of this two-day focused workshop are to discuss:
  1. the low-energy capabilities of DUNE,
  2. the recent status of supernova physics, and
  3. the potential impacts of DUNE for unraveling the physics of supernovae in future Galactic core-collapse neutrino datasets, including the physics of cross sections and backgrounds that are required to deliver science.

The workshop will bring together theorists and experimentalists at this exciting intersection, and will be modeled to provide a venue for stimulating exchange of scientific ideas and information among experts in different areas.

        Gadolinium in water Cherenkov detectors improves detection of supernova electron neutrino
        Detecting supernova $\nu_e$ is essential for testing supernova and neutrino physics, but the yields are small and the backgrounds from other channels large, e.g., $\sim 10^2$ and $\sim 10^4$ events, respectively, in Super-Kamiokande. We develop a new way to isolate supernova $\nu_e$, using gadolinium-loaded water Cherenkov detectors. The forward-peaked nature of $\nu_e + e^- \rightarrow \nu_e + e^-$ allows an angular cut that contains the majority of events. Even in a narrow cone, near-isotropic inverse beta events, $\bar{\nu}_e + p \rightarrow e^+ + n$, are a large background. With neutron detection by radiative capture on gadolinium, the background events can be individually identified with high efficiency. The remaining backgrounds are smaller and can be measured separately, so they can be statistically subtracted. Super-Kamiokande with gadolinium could measure the total and average energy of supernova $\nu_e$ with $\sim$ $20\%$ precision or better each ($90\%$ C.L.). Hyper-Kamiokande with gadolinium could improve this by a factor of $\sim$ 5. This precision will allow powerful tests of supernova neutrino emission, neutrino mixing, and exotic physics. Unless very large liquid argon or liquid scintillator detectors are built, this is the only way to guarantee precise measurements of supernova $\nu_e$.
