Recent results from T2K
  The T2K long-baseline neutrino oscillation experiment has produced the first observation of $\nu_{e}$ appearance and the most precise measurement of the mixing angle $\theta_{23}$ from $6.57 \times 10^{20}$ protons-on-target (POT) of neutrino beam data. We present here the results of T2K antineutrino oscillation analyses searching for $\bar{\nu}_{e}$ appearance and measuring the dominant oscillation parameters for $\bar{\nu}_{\mu}$ disappearance, including the results from the T2K near detector fit. Using $4.01 \times 10^{20}$ POT of antineutrino beam data T2K measured $\sin^{2}(\bar{\theta}_{23}) = 0.45^{+0.29}_{-0.12}$ and $|\Delta \bar{m}^{2}_{32}| = 2.51\pm0.28 \times 10^{-3} (eV^{2})$, consistent with previous existing $\nu_{\mu}$ and $\bar{\nu}_{\mu}$ disappearance measurements. From the same dataset 3 $\bar{\nu}_{e}$ candidate events were selected at the far detector, which did not provide evidence either for or against the $\bar{\nu}_{e}$ appearance hypothesis.
