Abstract
We present a three-flavour fit to the recent \nu\mu --> \nu e and \nu\mu --> \nu\mu T2K 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 (\theta_{13},\delta_{CP}) and (\theta_{23},\Delta m^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.
