Description
T2K oscillation physics results using an analysis which for the first time simultaneously fits the T2K dataset of νμ → νe appearance and νμ → νμ disappearance are shown. The precise T2K constraints on the four relevant oscillation parameters (sin^22θ_13, δ_CP , sin^2θ_23, and ∆m^2_32) are all correctly accounted for in this fit. In this analysis, the systematic errors are implemented in a simple manner, where all errors are encoded in a single systematic error covariance matrix, and confidence intervals are evaluated either at constant levels of ∆χ2 assuming Gaussian errors, or using frequentist methods.
