In this addendum to Schwetz et al (2011 New J. Phys. 13 063004), we consider the recent results from long-baseline νμ → νe searches at the Tokai to Kamioka (T2K) and Main Injector Neutrino Oscillation Search (MINOS) experiments and investigate their implications for the mixing angle θ13 and the leptonic Dirac CP phase δ. By combining the 2.5σ indication for a nonzero value of θ13 coming from the T2K data with global neutrino oscillation data, we obtain a significance for θ13 > 0 of about 3σ with best fit points sin2 θ13 = 0.013 (0.016) for normal (inverted) neutrino mass ordering. These results depend somewhat on assumptions concerning the analysis of reactor neutrino data.

- Current unknowns in the three-neutrino framework (2018, background): “Since the review in [1] (when only θ12 and θ23 were measured), dramatic progress has occurred concerning θ13 [15], starting from hints from solar, reactor and atmospheric data [16], to growing evidence from accelerator data [17, 18, 19, 20] and finally to its discovery and precise determination via ”
