Here we present our most updated global fit of neutrino oscillations including the recent results which have appeared since the Neutrino-2012 conference. These include the measurements of reactor anti-neutrino disappearance reported by Daya Bay and RENO, together  with latest T2K and MINOS data including both disappearance and appearance channels.

We also include the revised results from the third solar phase of Super-Kamiokande, SK-III, as well as new solar results from the fourth phase of Super-Kamiokande, SK-IV.

We find that the preferred global determination of the atmospheric angle θ23 is consistent with maximal mixing. We also determine the impact of the new data upon all the other neutrino oscillation parameters with emphasis on the increasing sensitivity to the CP phase, thanks to the interplay between accelerator and reactor data.

The most updated version of our analysis, including the new reactor data presented at the Neutrino-2014 conference is available on the arxiv server: arXiv:1405.7540. It has been published in Physical Review D.

Neutrino oscillation parameters summary. For Δm231, sin2θ23, sin2θ13, and δ the upper (lower) row corresponds to normal (inverted) neutrino mass hierarchy.

 

χ² results:

Δχ2 profiles as a function of all the neutrino oscillation parameters sin2θ12, sin2θ23, sin2θ13, Δm221, Δm231 and the CP phase δ. For the central and right panels the solid lines correspond to the case of normal mass hierarchy while the dashed ones correspond to inverted mass hierarchy.
