Revisiting the T2K data using different models for the neutrino-nucleus cross sections

Abstract

We present a three-flavour fit to the recent νμ--> νe and νμ--> νμT2K oscillation data with different models for the neutrino-nucleus cross section. We show that, even for a limited statistics, the allowed regions and best fit points in the (θ_{13},δ_{CP}) and (θ_{23},Δm^2_{atm}) planes are affected if, instead of using the Fermi Gas model to describe the quasielastic cross section, we employ a model including the multinucleon emission channel.
