Abstract
The T2K (Tokai to Kamioka) experiment is a long-baseline neutrino experiment designed to study the oscillations of accelerator-produced muon neutrinos and antineutrinos over a 295 km baseline from the J-PARC accelerator to the Super-Kamiokande detector in Japan. The primary goal is the precise measurement of the neutrino PMNS oscillation parameters, notably the mixing angles $\theta_{13}$, $\theta_{23}$, the mass-squared splitting $\Delta m^2_{32}$, and to probe the CP-violating phase $\delta_{\text{CP}}$. This paper presents the latest oscillation results from T2K, based on an exposure of $2.14 \times 10^{21}$ protons on target (POT) in neutrino mode and $1.63 \times 10^{21}$ POT in antineutrino mode. Key updates compared to the previous analysis include an additional $0.17 \times 10^{21}$ POT of neutrino data collected with Super-Kamiokande filled with Gadolinium (Gd) for the very first time, improvements in the systematic uncertainties at the far detector, and an additional robustness study of the neutrino interaction model.
