The observation of the recent electron neutrino appearance in a muon neutrino beam and the high-precision measurement of the mixing angle [math] have led to a re-evaluation of the physics potential of the T2K long-baseline neutrino oscillation experiment. Sensitivities are explored for CP violation in neutrinos, non-maximal [math], the octant of [math], and the mass hierarchy, in addition to the measurements of [math], [math], and [math], for various combinations of [math]-mode and [math]-mode data-taking.

With an exposure of [math] protons-on-target, T2K can achieve 1[math] resolution of 0.050 (0.054) on [math] and [math] on [math] for 100% (50%) neutrino beam mode running assuming [math] and [math]. T2K will have sensitivity to the CP-violating phase [math] at 90% C.L. or better over a significant range. For example, if [math] is maximal (i.e. [math]) the range is [math] for normal hierarchy and [math] for inverted hierarchy. When T2K data is combined with data from the NO[math]A experiment, the region of oscillation parameter space where there is sensitivity to observe a non-zero [math] is substantially increased compared to if each experiment is analyzed alone.
