Description
Neutrino-induced pion production on nuclei is an important contribution to the observable signal in neutrino experiments which are exposed to intense neutrino beams with energies ranging from a few 100-MeV to several GeV.
An accurate description of this processes is crucial for oscillation analysis, but on the other hand these experiments provide a unique window to the axial structure of the nucleon.
I will present several approaches and recent work on neutrino-induced pion production off nuclei, and discuss the main uncertainties which are related to the knowledge of the axial current, and the isospin separation of the vector current contribution.
I will present a tentative possibility to set constraints based on assumptions of quark-hadron duality.
