Subject: Neutrino-Nucleus Coherent Pion Production at MINERvA

Neutrino-nucleus coherent pion production is a rare neutrino scattering process that produces a lepton and pion in the forward direction while leaving the target nucleus in its initial state. Despite being rare, coherent pion production is an important background to neutrino oscillation measurements. Previous measurements of coherent pion production in the 1 to 10 GeV neutrino energy range, the energy range in which neutrino oscillation experiments operate, have been limited by either low statistics or detector capabilities. MINERvA, a dedicated neutrino-nucleus scattering experiment, has made precise measurements of neutrino and antineutrino charged current coherent pion production on carbon at 2 to 20 GeV neutrino energies. These measurements are an important input to neutrino-nucleus interaction models utilized by neutrino oscillation experiments.
