Description
The T2K experiment is a long base-line neutrino experiment located in Japan. Having successfully discovered $\nu_{e}$ appearance from a $\nu_{\mu}$ beam, T2K is now aimed at probing CP violation in the lepton sector, the mass hierarchy, and the precision measurement of $\sin^2{\theta_{23}}$. Since data taking started in 2010, T2K has accumulated $14.7\times10^{20}$ protons on target (POT) in neutrino beam mode, and $7.6\times10^{20}$ POT in antineutrino beam mode.
A new reconstruction algorithm for Super-Kamiokande (SK) -- the far detector of T2K -- is being used for event selection for the first time. The SK fiducial volume has been expanded,increasing the statistics by $\sim20\%$ from the previous selection with the same beam exposure. The latest developments in the T2K oscillation analysis within the PMNS framework, especially the measurement of $\delta_{CP}$, will be presented, and details of the analysis will be discussed.
