Axial form factor and neutrino-nucleus cross sections*

Neutrino-nucleus cross sections in the GeV energy range suffer from large uncertainties, yet good knowledge of these cross sections is essential for the success of the current and next generation of neutrino experiments, particularly DUNE, the Deep Underground Neutrino Experiment. In this talk, we study the impact of different assumptions concerning the axial form factor on the neutrino-nucleus cross-section prediction. In particular, we consider the very precise recent lattice calculations of this form factor. These new results will help to disentangle the hadronic from the nuclear effects.
