Description

The neutrino facility in the Japan Proton Accelerator Research Complex (J-PARC) produces a very intense neutrino beam for the Tokai to Kamioka long-baseline neutrino oscillation experiment, T2K. The physics operation of the T2K started in January 2010 and the data taken from the January 2010 to March 2011 period correspond to 1.43 × 1020 protons on target. From analysis of these data, the first νμ → νe appearance candidates were observed and an indication of sin22θ13 ≠ 0 was obtained with 2.5σ significance. The T2K aims for a very precise measurement of νe appearance and a possible search for CP violation with very large statistics. (author)
