Cross section status and needs of the LArTPC neutrino experiments

In this talk I will present the current status of cross section knowledge and their impacts on neutrino oscillation experiments. Both leptonic and hadronic energy reconstruction will be analyzed. I will review recent studies on impact of cross section and nuclear model uncertainties in the determination of neutrino oscillation parameters and I will present a viable way to tackle this hard problem using electron scattering data. Jefferson Lab approved and run a new argon (e,e'p) experiment in 2017 and first results were published by the E12-14-012 collaborations this year. These results will be very useful for the neutrino and nuclear theory community to model and validate models of neutrino-nucleus interactions.
