Title: Towards mono-energetic virtual neutrino beam cross-section measurements: A feasibility study of neutrino-Ar interaction analysis with DUNE-PRISM

Abstract: Neutrino-nucleus cross-section measurements are vital for future neutrino oscillation analyses. However, our models to describe them require further refinement, and a deeper understanding of the underlying physics is essential in order for future neutrino oscillation experiments to realize their ambitious physics goals. Using the DUNE-PRISM concept - a movable near detector that samples multiple off-axis positions - neutrino interaction measurements can be used to construct narrow virtual fluxes (less than 100 MeV wide). These fluxes can be used to extract charged-current neutrino-nucleus cross section as functions of outgoing lepton kinematics within specific neutrino energy ranges. Based on a dedicated simulation with realistic event statistics and flux-related systematic uncertainties, we demonstrate that DUNE-PRISM data can be used to measure muon neutrino charged-current integrated and differential cross sections over narrow fluxes.…
