Precision Measurements of the PMNS Parameters with T2K Data

T2K is a long baseline neutrino experiment which exploits a neutrino and antineutrino beam at JPARC to perform precision measurements of neutrino oscillation parameters $Δ{\rm m}^2_{\rm 32}$, $\sin^2 θ_{23}$ (besides the CP-violating phase $δ_{\rm CP}$). The latest results for the measurement of PMNS parameters in the disappearance mode are presented here, highlighting the main systematic uncertainties limiting the precision. The future strategy to improve the precision on the measurement of PMNS parameters are also discussed.
