Description
The T2K long-baseline neutrino oscillation experiment is composed of a near detector
at 280m and a far detector at Super-Kamiokande located 295 km from the neutrino beam
in Tokai. The main oscillation analyses are performed
using fits to the data collected at the far detector. These analyses depend on our
ability to predict the event rates and energy spectra at the far detector, which in
turn depend on cross-section and flux uncertainties. We use inputs from
external data, such as MiniBooNE and MINER$\nu$A, as well as beam flux measurements to
generate prior estimates of these uncertainties. T2K's near detector then provides
a direct internal constraint on the convolution of the flux and cross-section,
significantly reducing the uncertainties. This talk will discuss how data from the
near detector on T2K is used to constrain the oscillation analysis inputs.
