Measurement of $\hat{I}{½}_{\hat{I}}¼$ and $\bar{\hat{I}}{½}_{\hat{I}}¼$ Neutral Current $\ddot{I}{€}^0\to {\hat{I}}^3{\hat{I}}^3$ Production in the ArgoNeuT Detector

Abstract

The ArgoNeuT collaboration reports the first measurement of neutral current $\ddot{I}{€}^0$ production in $\hat{I}{½}_{\hat{I}}¼$-argon and $\bar{\hat{I}}{½}_{\hat{I}}¼$-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 $\hat{I}{½}_{\hat{I}}¼$ of 9.6~GeV and for $\bar{\hat{I}}{½}_{\hat{I}}¼$ of 3.6~GeV. We compare the measured cross section and kinematic distributions to predictions from the GENIE and NuWro neutrino interaction event generators.
