Title: The T2K Experiment

Abstract

T2K is a long-baseline neutrino oscillation experiment built to make precision measurements of θ{sub 13}, θ{sub 23} and Δm{sup 2}{sub 32}. It achieves this by utilising an off-axis, predominantly ν{sub µ}, neutrino beam from J-PARC to Super-Kamiokande, and a near detector complex which constrains the beam’s direction, flux, composition and energy. To date T2K has published ν{sub µ}-disappearance and ν{sub e}-appearance results, the latter excluding θ{sub 1}3 = 0 at over 3σ and therefore constituting first evidence for ν{sub e}-appearance in a ν{sub µ} beam. In addition to oscillation physics, the on-axis (INGRID) and off-axis (ND280) near detectors provide the capability for a broad neutrino-nucleus interaction physics programme at neutrino energies below 1GeV.
