Pion production is one of the primary processes by which neutrinos are identified in running oscillation experiments such as Nova [1] and in future experiments like DUNE [2]. The MINERvA collaboration [3] has completed one NC (neutral current) and a few CC (charged current) measurements of this type using a CH (hydrocarbon plastic scintillator) target, from which four outstanding papers have been published. One of them is the CC coherent pion production, an important background for CCQE interactions in neutrino oscillation experiments, has been measured in both neutrino and anti-neutrino beams. The inelastic pion production cross section is much larger, and a more comprehensive data set for both π + and π 0 , also with neutrino and antineutrino beams is available. The other two are the CC single neutral pion and the NC diffractive neutral pion interactions, which are very rare and almost unstudied channels. All four reactions are also very interesting in their own right due to their potential to probe nuclear models. Data compared with available theoretical calculations and models, are presented here.
