Measurement of the Antineutrino Neutral-Current Elastic Differential Cross Section

Abstract

We report the measurement of the flux-averaged antineutrino neutral current elastic scattering cross section ($dσ_{\bar νN \rightarrow \bar νN}/dQ^{2}$) on CH$_{2}$ by the MiniBooNE experiment using the largest sample of antineutrino neutral current elastic candidate events ever collected. The ratio of the antineutrino to neutrino neutral current elastic scattering cross sections and a ratio of antineutrino neutral current elastic to antineutrino charged current quasi elastic cross section is also presented.
