| الوصف: | Neutrino-induced coherent charged pion production on nuclei, $\stackrel{(-)}{\nu}_\mu A\to\mu^\pm\pi^\mp A$ is a rare, inelastic interaction in which a small squared four-momentum $| t|$ 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 $| t|$ from the final state pion and muon. We select low $| t|$ events to isolate a sample rich in coherent candidates. By selecting low $| t|$ 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. Comment: 13 pages, 4 figures. v3->v4 corrections to several inline formulas and fixes to citations. v2->v3 revision includes minor corrections to text and tables, the final ArgoNeuT result in Figure 3, and ancillary files with the tables in CSV format. v1->v2 revision added comparisons to NEUT generator and updated estimate of the diffractive-like process on protons |
