AbstractWe present a global analysis of neutrino oscillation data, including in particular the high-precision measurements of the last SM mixing angle θ13 at reactors, which have confirmed previous indications in favor of θ13>0. We focus on the correlations between θ13 and the mixing angle θ23, as well as between θ13 and the neutrino CP-violation phase δ. Assuming normal hierarchy, we find possible hints about the other two unknowns, namely: a slight preference for the first θ23 octant, and a possible indication for non-zero CP violation (with sin δ<0), although at the level below 2σ for both the two cases. Note that the second hint appears also in inverted hierarchy, but with even lower statistical significance. No palpable difference between normal and inverted mass hierarchy emerges from the data.
