Query: Measurement of $\nu_{\mu}$ and $\bar{\nu}_{\mu}$ Neutral Current
  $\pi^{0} \rightarrow \gamma\gamma$ Production in the ArgoNeuT Detector   The ArgoNeuT collaboration reports the first measurement of neutral current
$\pi^{0}$ production in $\nu_{\mu}$-argon and $\bar{\nu}_{\mu}$-argon
scattering. This measurement was performed using the ArgoNeuT liquid argon time
projection chamber deployed at Fermilab's NuMI neutrino beam with an exposure
corresponding to 1.2$\times 10^{20}$ protons-on-target from the Fermilab Main
Injector and a mean energy for $\nu_{\mu}$ of 9.6~GeV and for $\bar{\nu}_{\mu}$
of 3.6~GeV. We compare the measured cross section and kinematic distributions
to predictions from the GENIE and NuWro neutrino interaction event generators.
