Status and prospects of global analyses of neutrino mass-mixing parameters

Abstract

We discuss the present knowledge of the neutrino oscillation parameters, the two mass squared differences (δm2, Δm2), the three mixing angles (θ12, θ13, θ23) 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 ordering are still undetermined. We update our previous analysis, by adding to the global fit the recent results presented at The XXVII International Conference on Neutrino Physics and Astrophysics (Neutrino 2016) by the experiments T2K, NOνA, Super-Kamiokande, Daya Bay and RENO.
