Abstract

Neutrino-induced coherent charged pion production on nuclei, ν(−)μA→μ±π∓A\stackrel{(-)}{\nu}_\mu A\to\mu^\pm\pi^\mp A is a rare, inelastic interaction in which a small squared four-momentum ∣t∣| t| is transferred to the recoil nucleus leaving it intact in the reaction. In the scintillator tracker of MINERvA, we remove events with evidence of particles from nuclear breakup and reconstruct ∣t∣| t| from the final state pion and muon. We select low ∣t∣| t| events to isolate a sample rich in coherent candidates. By selecting low ∣t∣| t| events we produce a model-independent measurement of the differential cross section for coherent scattering of neutrinos and anti-neutrinos on carbon. We find poor agreement with the predicted kinematics in neutrino generators used by current oscillation experiments.
