Description
T2K is an off-axis long-baseline neutrino experiment, using the J-PARC muon-neutrino beam to look for muon-neutrino disappearance (to measure $\theta_{23}$ and $\Delta m^2_{32}$) and electron-neutrino appearance (to measure $\theta_{13}$). Super-Kamiokande, a 22.5 kton fiducial water Cerenkov detector located 295 km from the neutrino source, is used as the far detector. I report the result of the muon-neutrino disappearance search, using data up to summer 2012. The best-fit value of the oscillation parameters gives $|\Delta m^{2}_{32}| = 2.44 \times 10^{-3} eV^2$ and $\sin^{2}2\theta_{23} = 1.00$, and the 90% C.L. exclusion region is competitive with other experiments.
