Abstract
Studying the neutrino cross sections of various materials is of great importance in the analysis of data from neutrino oscillation experiments, as well as interesting in its own right. We have examined the charged-current muon neutrino cross section ratio between lead and scintillator, with our lead target being in the MINERvA electromagnetic calorimeter. This choice has allowed us to obtain usable efficiencies out to much larger muon angles than was feasible from the upstream targets. Comparing the cross section ratio in the data and Monte Carlo, we have found that the ratios agree reasonably well as a function of neutrino energy, but with a distinct excess at low energies. However, there are significant differences between data and Monte Carlo at low and high values of Bjorken x.
