Global Analysis of 3 Flavour Neutrino Oscillations

In this talk I presented the main results of the latest global analysis of the three-flavour neutrino oscillations performed by the NuFit collaboration, which is focused on the study of the complementarity and tension among the neutrino oscillation experimental data, available as of fall 2018, in the determination of θ$_{23}$ and δ$_{CP}$ parameters and the mass ordering. A tabulated Δχ$^{2}$ of the Super-Kamiokande atmospheric neutrino data analysis within the same oscillation framework, provided by the collaboration, is added to the global analysis. Without (with) Super-Kamiokande atmospheric neutrino tabulated Δχ$^{2}$ , a preference for normal mass ordering is found at the Δχ$^{}$ = 4.7(9.3) level. The second octant of θ$_{23}$ is preferred with respect to the first one with Δχ$^{2}$ = 4.4(6.0). A tension in NOvA $\bar{v}$ and T2K data when determining δ$_{CP}$ for normal mass ordering, makes CP conservation being disfavour only with Δχ$^{2}$ = 1.5(1.8).
