The T2K long-baseline neutrino oscillation experiment has produced the first observation of νe appearance and the most precise measurement of the mixing angle θ23 from 6.57 × 1020 protons-on-target (POT) of neutrino beam data. We present here the results of T2K antineutrino oscillation analyses searching for ¯ νe appearance and measuring the dominant oscillation parameters for ¯ νμ disappearance, including the results from the T2K near the detector fit. Using 4.01 × 1020 POT of antineutrino beam data T2K measured sin2(¯ θ23)=0 .45+0.29 −0.12 and |Δ¯ m232| =2 .51±0.28×10−3(eV2), consistent with previous existing νμ and ¯ νμ disappearance measurements. From the same dataset 3 ¯ νe candidate events were selected at the far detector, which did not provide evidence either for or against the ¯ νe appearance hypothesis.
