We investigate the expected precision of the reconstructed neutrino direction
using a {\nu}{\mu}-argon quasielastic-like event topology with one muon and one
proton in the final state and the reconstruction capabilities of the MicroBooNE
liquid argon time projection chamber. This direction is of importance in the
context of DUNE sub-GeV atmospheric oscillation studies. 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 x 1021 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 {\nu}{\mu} quasielastic-like scattering
on argon as a function of the muon-proton system angle using the full
MicroBooNE data sets. We also demonstrate the sensitivity of these results to
nuclear effects and final state hadronic reinteraction modeling.

Cet article explore les excursions dans le temps et leurs implications.
