Measurement of ${\nu }_{\mu }$ and ${\bar{\nu }}_{\mu }$ Neutral Current ${\pi }^0\to \gamma \gamma$ Production in the ArgoNeuT Detector

Abstract

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.
