## The latest results from the T2K long baseline neutrino oscillation experiment.

### 2011/Jun./14

The T2K is the neutrino oscillation experiment by using muon neutrino beam produced by the accelerator complex JPARC and the water Cherenkov detector Super-Kamiokande located at 295 km distance. We searched for $\nu_\mu \rightarrow \nu_e$ appearance signal in the data taken from January 2010 until March 2011, corresponding to an exposure of $1.43 \times 10^{20}$ proton on target. The exposure is about five times larger than that of the previous report. In the seminar, the results of the search for $\nu_e$ appearance in the T2K experiment will be reported.

The T2K is organizing two simultaneous seminars in KEK and ICRR, to report the new results.
