Abstract
We search in the MINERvA scintillator detector for multiple proton emission in quasielastic like charged current neutrino scattering. The number of such observable events in MINERvA is predicted to be far greater than currently available samples. We measure the total number of such events, and study the distribution of laboratory frame angles between the multiple protons and the muon, which is sensitive to the production mechanism for such events. We find significant disagreement of signal events between data and Monte-Carlo simulation.
