MINERvA has measured the νµ-induced coherent π + cross section simultaneously in hydrocarbon (CH), graphite (C), iron (Fe) and lead (Pb) targets using neutrinos from 2 to 20 GeV. The measurements exceed the predictions of the Rein-Sehgal and Berger-Sehgal PCAC based models at multi-GeV νµ energies and at produced π + energies and angles, Eπ > 1 GeV and θπ < 10 • . Measurements of the cross-section ratios of Fe and Pb relative to CH reveal the effective A-scaling to increase from an approximate A 1/3 scaling at few GeV to an A 2/3 scaling for Eν > 10 GeV.
