| The reconstructed neutrino energy distributions for neutrino (top) and antineutrino (bottom) mode 1R$\mu$ samples. The lines show the predicted number of events under two hypotheses: ``Joint $\nu_{e}$ + $\nu_{\mu}$ analysis'' uses the best-fit values from a joint analysis of the PMNS model to electron-like and muon-like samples\cite{T2K:2023smv}, ``3-flavor $\nu_{\mu}$ analysis'' (this analysis) uses the best-fit from the analysis reported here. The error bars indicate the statistical uncertainties. |

| Confidence regions of ($\sin^2\theta_{23}, \Delta m^{2}_{32}$) for neutrinos and their barred parameters for antineutrinos. Corresponding regions from the standard PMNS formalism analysis~\cite{T2K:2023smv} including $\nue$ samples are also shown for comparison. |

| Comparison of the 90\% confidence level in ($\sin^2\theta_{23}, \Delta m^{2}_{32}$) and their barred counterparts for antineutrinos (dot-dashed lines) to those obtained in the previous analysis (red line), an intermediate step showing the contribution of the updated analysis model (blue line), and the final results of this analysis including new SK neutrino mode data and updated data processing (green line). |
