Understanding the energy resolution of liquid-argon neutrino detectors

by Dr Shirley Li (FNAL)


Understanding particle energy resolution is essential for accurately predicting the performance of DUNE. In this talk, I will describe our study to connect energy resolution to the underlying physical processes. We first characterize the channels of non-hermeticity of DUNE, including subthreshold particles, charge recombination, and nuclear breakup. We paid particular attention to the role of neutrons, which are responsible for a significant fraction of missing energy in all channels. Next, we determine the energy resolution by quantifying event-to-event stochastic fluctuations in missing energy. This is done for several sets of assumptions about the reconstruction performance, including those available in the literature. Our framework can be used to assess the impact of cross-section uncertainties on oscillation sensitivity in the future.
