Electrons for Neutrinos: Analysis of the 1p1pi Channel

Neutrino oscillation is of particular interest to experiments around the world. The oscillation of the neutrino is measured as a function of the particle's energy divided by propagation distance. This energy (E), however, is not directly measurable and must instead be reconstructed from the momenta of particles knocked out during neutrino-nucleus interactions. In order to test this energy reconstruction, we exploited the similarity between electron-nucleus and neutrino-nucleus interactions using electron-nucleus scattering data collected by the large-acceptance CLAS6 detector at the Thomas Jefferson National Accelerator Facility. This presentation will focus on the resonance dominated 1p1pi channel and we will present results on pi+ and pi- and compare them to Genie calculations. This data will be used to guide improvements in current event generators which are important to meet the requirements of high-precision experiments currently underway at facilities such as MicroBooNE, MINERvA, DUNE, and T2K.
