MicroBooNE is the first of three liquid-argon time projection chambers (LArTPC) in the Fermilab Short Baseline Neutrino Program, which is aiming to probe the electron neutrino like event excess observed by the LSND and MiniBooNE experiments. In parallel, MicroBooNE has a rich cross section physics program to study neutrino-argon interactions in the energy range of 100 MeV to 2 GeV. In this seminar I will present the measurement of the muon neutrino charged-current inclusive cross section on argon. This is one of the very first measurements from MicroBooNE, and the very first neutrino-argon cross section on argon at low neutrino energies. 

LArTPCs are state-of-the-art detectors for neutrino physics, and have a high spatial resolution. I will present how the MicroBooNE LArTPC allows for a measurement with full angular and momentum acceptance, that can be easily compared to theory models and other experiments. The results will support the understanding of normalization constraints for the oscillation analysis. 

I will present techniques for selecting charged-current muon neutrinos and rejection of the dominant cosmic muon backgrounds, and the extracted neutrino-argon cross section as a function of muon momentum and angle.
