In the past few years new published data for the pion production became avialable and a number of preliminary results have been reported based on the large samples of the neutrino interactions observed by the K2K, MiniBooNE and SciBooNE experiments. The new results might help to understand the long-standing discrepancy in four-momentum transfer observed between observed charged current pion production data and existing predictions as well as the difference in observed coherent pion production due to the neutral and charged currents. Pion production as a dominant background for the quasielastic interaction in a few GeV neutrino energy range is essential for experiments measuring neutrino oscillation parameters .
I will present an overview of the recent measurements of pion production reported by K2K, MiniBooNE and SciBooNE collaborations.
