description: The T2K experiment measures muon neutrino disappearance and electron neutrino appearance in accelerator-produced neutrino and antineutrino beams. With an exposure of $14.7(7.6)\times 10^{20}$ protons on target in neutrino (antineutrino) mode, 89 $ν_e$ candidates and 7 anti-$ν_e$ candidates were observed while 67.5 and 9.0 are expected for $δ_{CP}=0$ and normal mass ordering. The obtained $2σ$ confidence interval for the $CP$ violating phase, $δ_{CP}$, does not include the $CP$-conserving cases ($δ_{CP}=0,π$). The best-fit values of other parameters are $\sin^2θ_{23} = 0.526^{+0.032}_{-0.036}$ and $Δm^2_{32}=2.463^{+0.071}_{-0.070}\times10^{-3} \mathrm{eV}^2/c^4$.
