Description
The neutrino direction reconstruction is of importance in the context of DUNE sub-GeV atmospheric oscillation studies. In this work, we investigate the expected precision of the reconstructed neutrino direction using a 𝜈𝜇-argon quasielasticlike event topology with one muon and one proton in the final state in the MicroBooNE liquid argon time projection chamber. MicroBooNE allows for a data-driven quantification of this resolution by investigating the deviation of the reconstructed muon-proton system orientation with respect to the well-known direction of neutrinos originating from the Booster Neutrino Beam with an exposure of 1.3 ×10^21 protons on target. Using simulation studies, we derive the expected sub-GeV DUNE atmospheric-neutrino reconstructed simulated spectrum by developing a reweighting scheme as a function of the true neutrino energy. We further report flux-integrated single- and double-differential cross section measurements of charged-current 𝜈𝜇 quasielasticlike scattering on argon as a function of the muon-proton system angle using the full MicroBooNE data sets.
