  We report on a flux-integrated multi-differential measurement of
charged-current muon neutrino scattering on argon with one muon and one proton
in the final state using the Booster Neutrino Beam and MicroBooNE detector at
Fermi National Accelerator Laboratory. The data are studied as a function of
various kinematic imbalance variables and of a neutrino energy estimator, and
are compared to a number of event generator predictions. We find that the
measured cross sections in different phase-space regions are sensitive to
nuclear effects. Our results provide precision data to test and improve the
neutrino-nucleus interaction models needed to perform high-accuracy oscillation
analyses. Specific regions of phase-space are identified where further model
refinements are most needed.
