The T2K neutrino oscillation experiment has been taking data
since the beginning of the year, and several neutrino beam events have
been observed in the Super-K detector, 295 km from the J-Parc
accelerator and the ND280 detector. The main goals of the experiment
are to measure the disappearance of muon neutrinos and the appearance
of electron neutrinos, as well as precise measurements of
neutrino-nucleon interactions. A positive appearance signal would make
it possible to search for neutrino CP-violation. The expected
sensitivity to oscillation parameters are presented in the context of
the many unanswered questions that prevail in the neutrino sector of
the standard model
