Abstract

The MiniBooNE experiment at Fermilab has amassed the largest sample to date of π⁰s produced in neutral current (NC) neutrino-nucleus interactions at low energy. This Letter reports a measurement of the momentum distribution of π⁰s produced in mineral oil (CH₂) and the first observation of coherent π⁰ production below 2 GeV. In the forward direction, the yield of events observed above the expectation for resonant production is attributed primarily to coherent production off carbon, but may also include a small contribution from diffractive production on hydrogen. Integrated over the MiniBooNE neutrino flux, the sum of the NC coherent and diffractive modes is found to be (19.5 ± 1.1 (stat) ± 2.5 (sys)) % of all exclusive NC π⁰ production at MiniBooNE. These measurements are of immediate utility because they quantify an important background to MiniBooNE's search for ν_μ → ν_e oscillations.
