Present Status of Single Pion Production in Neutrino-Nucleus Reactions

Abstract

Some of the recent progress in the physics of pion production induced by neutrinos on nucleons and nuclei is reviewed from a theoretical perspective. The importance of Watson's theorem to reconcile ANL and BNL data with the off-diagonal Goldberger-Treiman relation for the $\Delta (1232)$ is discussed. The disagreement between MiniBooNE data and theoretical calculations is presented in the light of the new MINERvA data. The coherent pion production data on ${}^{12}$C obtained by MINERvA are also compared to different microscopic and PCAC models.
