New Neutrino Cross-Section Measurements in T2K

<p>We describe how the T2K near detectors are used to measure the neutrino interaction cross sections necessary for T2K to reach the final precision for its νe-appearance and νμ-disappearance results. We then present the new near detector cross section results, for charged current inclusive and exclusive scattering and neutral current pi0 production. We will also describe new observables developed recently to increase sensitivity to the cross-section model and the most recent developments on the neutrino-nucleus cross-section modelling by the T2K collaboration. The T2K Near Detector upgrade program and its relation to uncertainties in cross-section modelling will be also discussed.
