Neutrino-nucleus interactions in the T2K experiment

We present a study of neutrino-nucleus interactions at the T2K experiment based on the GiBUU transport model. The aim of T2K is to measure ${\nu }_e$ appearance and ${\theta }_{13}$, but it will also be able to do a precise measurement of ${\nu }_{\mu }$ disappearance. The former requires a good understanding of ${\pi }^0$ production while the latter is closely connected with a good understanding of quasielastic scattering. For both processes we investigate the influence of nuclear effects and particular final-state interactions on the expected event rates taking into account the T2K detector setup.
