T2K is a long baseline neutrino experiment producing a beam of muon neutrinos and antineutrinos at the Japan Particle Accelerator Research Centre (JPARC) and measuring their oscillation by comparing the measured neutrino rate and spectrum at a near detector complex, located at JPARC, and at the water-Cherenkov detector Super Kamiokande, located 295 Km away.
Such intense neutrino beam and the set of near and far detectors offer a unique opportunity to measure neutrino cross-sections for interactions on different nuclei (C and O primarily), for different neutrino energies and flavours. In particular, the combination of near detectors at different off-axis angles, enable an improved control on the energy-dependence of the neutrino cross-section. T2K is also pioneering new analysis techniques which target the exclusive measurement of the neutrino-interaction final state, including the kinematics of its hadronic part. An overview of the most recent T2K cross-section analyses will be presented, including a new measurement of coherent pion production in neutrino and antineutrino scattering on Carbon nuclei.
