AB - The T2K experiment presents new measurements of neutrino oscillation parameters using 19.7(16.3) ×1020 protons on target (POT) in (anti-)neutrino mode at thefar detector (FD). Compared to the previous analysis, anadditional 4.7 × 1020 POT neutrino data was collected atthe FD. Significant improvements were made to the analysis methodology, with the near-detector analysis introducing new selections and using more than double the data.Additionally, this is the first T2K oscillation analysis to useNA61/SHINE data on a replica of the T2K target to tune theneutrino flux model, and the neutrino interaction model wasimproved to include new nuclear effects and calculations.Frequentist and Bayesian analyses are presented, including results on sin2 θ13 and the impact of priors on the δCP measurement. Both analyses prefer the normal mass orderingand upper octant of sin2 θ23 with a nearly maximally CPviolating phase. Assuming the normal ordering and using theconstraint on sin2 θ13 from reactors, sin2 θ23 = 0.561+0.021 −0.032using Feldman–Cousins corrected intervals, and Δm232 =2.494+0.041−0.058 × 10−3 eV2 using constant Δχ2 intervals. TheCP-violating phase is constrained to δCP = −1.97+0.97 −0.70 usingFeldman–Cousins corrected intervals, and δCP = 0, π isexcluded at more than 90% confidence level. A Jarlskoginvariant of zero is excluded at more than 2σ credible levelusing a flat prior in δCP, and just below 2σ using a flat prior insin δCP. When the external constraint on sin2 θ13 is removed,sin2 θ13 = 28.0+2.8−6.5 × 10−3, in agreement with measurements from reactor experiments. These results are consistentwith previous T2K analyses.
