I present the latest results (Feb 2014) from the Tokai-to-Kamioka (T2K) long baseline neutrino oscillation experiment. At J-PARC, Japan’s newest particle physics facility, 30 GeV protons are collided on a graphite target to produce a beam of muon neutrinos with E = ~600 MeV. This beam is monitored and characterised by a suite of detectors 280 meters away before being sent 295 km through the Earth’s crust to the Super-Kamiokande detector. The full data set taken to date, consisting of 6.57×10^20 protons on target, has been analysed for both nu_mu disappearance and nu_e appearance. The disappearance analysis has produced a new level of precision in measuring the neutrino mixing parameter theta_23. The appearance analysis, in combination with reactor neutrino constraints of the theta_13 mixing angle, introduces the first constraints on the Dirac CP-violating phase delta. Finally, I conclude by presenting the future sensitivity of T2K in various potential configuration modes.
