The T2K long-baseline neutrino oscillation experiment has been running since January 2010, and has roughly doubled the data set in both neutrino and anti-neutrino beam mode since the most recent published results. We present a joint analysis of neutrino and anti-neutrino data, using both disappearance and appearance channels.

This analysis uses a new event reconstruction algorithm, an enlarged fiducial volume, and a new sample of electron-like events with tagged pion decays. The cross-section models used to analyse the data have also been updated to better treat multi-nucleon effects. We present newly-updated measurements of $\theta_{23}$ , $\Delta m^2_{23}$, $\theta_{13}$ and $\delta_\mathrm{CP}$, using an exposure of $1.49(1.12)\times10^{21}$ POT in Forward(Reverse) Horn Current mode. By requiring that the value of $\theta_{13}$ should be consistent with reactor neutrino measurements, CP-conserving hypotheses ($\delta_\mathrm{CP} = \{0,\pi\}$) are excluded at over $2\sigma$
