Abstract

Single neutral pion production via muon antineutrino charged-current interactions in plastic scintillator (CH) is studied using the \minerva detector exposed to the NuMI low-energy, wideband antineutrino beam at Fermilab. Measurement of this process constrains models of neutral pion production in nuclei, which is important because the neutral-current analog is a background for νˉe\bar{\nu}_e appearance oscillation experiments. The differential cross sections for π0\pi^0 momentum and production angle, for events with a single observed π0\pi^0 and no charged pions, are presented and compared to model predictions. These results comprise the first measurement of the π0\pi^0 kinematics for this process.
