Abstract

Using a high-statistics sample of neutral current elastic neutrino interactions, MiniBooNE measured the flux-averaged neutral current elastic differential cross-section on mineral oil ( $C H_{2}$ ). Using the latter, a $χ^{2}$ test of MC with different values of the axial vector mass has been performed. Also, a possibility of using a sample of neutral current elastic proton-enriched events above Cherenkov threshold to measure the ratio $ν p \to ν p / ν N \to ν N$ is discussed. This ratio is sensitive to the strange quark contribution to the nucleon spin, $Δ s$ .
