Abstract: 
T2K (Tokai to Kamioka) is a long baseline neutrino oscillation experiment. An intense muon neutrino beam is produced at J-PARC, on the east coast of Japan, and is directed 2.5 degrees off-axis to the Super-Kamiokande water Cherenkov detector, located 295 kilometres away in the alps of western Japan.
 
Recent results from the T2K experiment include a 7.3 sigma exclusion of the mixing angle theta_13 = 0; hints of delta, the CP-violating phase in the PMNS matrix; a world-leading measurement of the atmospheric mixing angle theta_23 and differential muon and electron neutrino cross-section measurements.
