Description
The talks aims to present the results of the first physics
run of T2K and give an update on the status and performance of the
experiment. T2K is the first long baseline off-axis neutrino
oscillation experiment and aims to refine the measurements of the
oscillation parameters Dm_23 and theta_23, discovered by Super-
Kamiokande with atmospheric neutrinos, respectively at a level of
10% and <1% uncertainties in disappearance neutrino oscillation
mode. Moreover these parameters are fundamental ingredients for the
key research item of T2K that is the discovery of theta_13 by
measuring the appearance of electron neutrinos, which is furthermore
needed to understand CP violation in the leptonic sector. This will be done by comparing the flux of a high intensity neutrino beam at a near detector station, ND280 (composed of on-axis and 2.5 degree off-axis detectors at roughly 280 m from the neutrino source) with the flux 2.5 degree off-axis
at the far detector, Super-Kamiokande (295 km from the source).
