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 νe​
appearance and θ13​, but it will also be able to do a precise
measurement of νμ​ disappearance. The former requires a good
understanding of π0 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.Comment: v3: matches version to be published in Phys. Rev.
