  The ArgoNeuT collaboration presents the first measurements of inclusive muon
neutrino charged current differential cross sections on argon. Obtained in the
NuMI neutrino beamline at Fermilab, the results are reported in terms of
outgoing muon angle and momentum. The data are consistent with the Monte Carlo
expectation across the full range of kinematics sampled,
$0^\circ$$<\theta_\mu$$<36^\circ$ and 0$<P_\mu$$<25$ GeV/c. Along with
confirming the viability of liquid argon time projection chamber technology for
neutrino detection, the measurements allow tests of low energy neutrino
scattering models important for interpreting results from long baseline
neutrino oscillation experiments designed to investigate CP violation and the
orientation of the neutrino mass hierarchy.
