Neutrino Physics and LArTPC R\&D with ArgoNeuT

Set to begin taking data in early 2008 in the on-axis NuMI neutrino beamline, ArgoNeuT is a Liquid Argon Time Projection Chamber (LArTPC) R\&D test stand for future CP Violation and $\theta_{13}$ neutrino oscillation searches. The first LArTPC to be placed in a ``low'' energy accelerator-based neutrino beam, ArgoNeuT will collect $\sim$10$^5$ neutrino events per year in the 0.1-10 GeV range (peaking at 3 GeV). The GEANT4 simulation framework and physics capabilitity of the detector will be presented. Including comparison to first events, simulation discussion will focus on using a dE/dx tag for electron and gamma separation, vital for $\nu_\mu$/$\nu_e$ tagging efficiency. Also, the possibility of $\nu_\mu$ charged current quasi-elastic cross section and M$_A$ parameter measurements will be discussed.
