In addition to its contributions to our understanding of neutrino oscillation
parameters, the T2K long-baseline neutrino oscillation experiment has a
complementary program of neutrino interaction cross-section measurements with
its near detector complex. With multiple targets (carbon, water, argon, iron),
and with on- and off-axis detectors which sample different neutrino spectra
from the same beamline, T2K is able to investigate atomic number and energy
dependent behavior in a single experiment.
This talk presents an overview of the T2K neutrino cross sections, focusing on
the latest results.
