Three-neutrino mixing: status and prospects

We discuss the present knowledge of the neutrino oscillation parameters. In a three-neutrino scenario, neutrino oscillations depend on six parameters, two squared mass differences (Δm², δm²), three mixing angles ( θ ₁₂, θ₁₃ , θ ₂₃) and one phase δ . While five out of these six parameters have been measured, the CP-violating phase δ remains unknown. Moreover, the octant of the mixing angle θ₂₃ and the neutrino mass hierarchy are still undetermined. We update our previous analysis, by adding to the global fit the recent results of the antineutrino running of T2K, the first results of the NO v A experiment, the latest SuperKamiokande and IceCube atmospheric neutrino data.
