  The ArgoNeuT collaboration presents measurements of inclusive muon neutrino
and antineutrino charged current differential cross sections on argon in the
Fermilab NuMI beam operating in the low energy antineutrino mode. The results
are reported in terms of outgoing muon angle and momentum at a mean neutrino
energy of 9.6 GeV (neutrinos) and 3.6 GeV (antineutrinos), in the range
$0^\circ < \theta_\mu < 36^\circ$ and $0 < p_\mu < 25$ GeV/$c$, for both
neutrinos and antineutrinos.
