Threeflavor oscillation parameters from our fit to global data as of May 2016. The results are presented for both 'LEM' (above) and 'LID' (below) choices of the NOνA ν_{e}appearance data. The normalization of reactor fluxes is left free and data from shortbaseline reactor experiments are included. The numbers in the 1st (2nd) column are obtained assuming NO (IO), i.e., relative to the respective local minimum, whereas in the 3rd column we minimize also with respect to the ordering. Note that Δm^{2}_{3ℓ} = Δm^{2}_{31} > 0 for NO and Δm^{2}_{3ℓ} = Δm^{2}_{32} < 0 for IO. 

3σ CL ranges of the magnitude of the elements of the threeflavour leptonic mixing matrix under the assumption of the matrix U being unitary, for both choices of the NOνA ν_{e}appearance data. The normalization of reactor fluxes is left free and data from shortbaseline reactor experiments are included. The ranges in the different entries of the matrix are correlated due to the fact that, in general, the result of a given experiment restricts a combination of several entries of the matrix, as well as to the constraints imposed by unitarity. As a consequence choosing a specific value for one element further restricts the range of the others. 
Twodimensional allowed regions
pdf jpg 
Global 3ν oscillation analysis. Each panel shows the twodimensional projection of the allowed sixdimensional region after marginalization with respect to the undisplayed parameters. The different contours correspond to the twodimensional allowed regions at 1σ, 90%, 2σ, 99%, 3σ CL (2 dof). The results are presented for both 'LEM' (colored regions) and 'LID' (black contours) choices of the NOνA ν_{e}appearance data. The normalization of reactor fluxes is left free and data from shortbaseline reactor experiments are included. Note that as atmospheric masssquared splitting we use Δm^{2}_{31} for NO and Δm^{2}_{32} for IO. The regions in the lower 4 panels are based on a Δχ^{2} minimized with respect to the mass ordering. 
Onedimensional χ^{2} projections
pdf jpg 
Global 3ν oscillation analysis. The red (blue) curves are for Normal (Inverted) Ordering. The results are presented for both 'LEM' (solid lines) and 'LID' (dashed lines) choices of the NOνA ν_{e}appearance data. The normalization of reactor fluxes is left free and data from shortbaseline reactor experiments are included. Note that as atmospheric masssquared splitting we use Δm^{2}_{31} for NO and Δm^{2}_{32} for IO. 
CPviolation: Jarlskog invariant
pdf jpg 
Dependence of Δχ^{2} on the Jarlskog invariant. The red (blue) curves are for NO (IO). The results are presented for both 'LEM' (solid lines) and 'LID' (dashed lines) choices of the NOνA ν_{e}appearance data. The normalization of reactor fluxes is left free and data from shortbaseline reactor experiments are included. 
CPviolation: unitarity triangles
pdf jpg 
The six leptonic unitarity triangles. After scaling and rotating each triangle so that two of its vertices always coincide with (0,0) and (1,0), we plot the 1σ, 90%, 2σ, 99%, 3σ CL (2 dof) allowed regions of the third vertex. The results are presented for both 'LEM' (colored regions) and 'LID' (black contours) choices of the NOνA ν_{e}appearance data. The normalization of reactor fluxes is left free and data from shortbaseline reactor experiments are included. Note that in the construction of the triangles the unitarity of the U matrix is always explicitly imposed. 
Tension between Solar and KamLAND data
pdf jpg 
Left: Allowed parameter regions (at 1σ, 90%, 2σ, 99%, 3σ CL for 2 dof) from the combined analysis of solar data for GS98 model (colored regions with best fit marked by black star) and AGSS09 model (dashed black contours with best fit marked by a white dot), and for the analysis of KamLAND data (solid green contours with best fit marked by a green star) for fixed θ_{13} = 8.5°. We also show as orange contours the results of a global analysis for the GS98 model but without including the daynight information from SK. Right: Δχ^{2} dependence on Δm^{2}_{21} for the same three analysis after marginalizing over θ_{12}. 
Tendencies: contribution of different data
pdf jpg 
Cumulative contribution of different sets of experimental results to the present tendencies in the determination of the mass ordering, the octant of θ_{23} and of the CP violating phase. Left (right) panels are for IO (NO). Violet: results of the NuFIT 2.0 analysis after updating the solar and reactor data. Blue: same as violet, plus IceCube/DeepCore atmospheric ν data. Green: same as blue, plus T2K ν_{μ}disappearance and ν_{e}appearance data. Red & orange: same as green, plus NOνA ν_{μ}disappearance and LEM (red) or LID (orange) ν_{e}appearance data. 
Tendencies: correlation between δ_{CP} and other parameters
pdf jpg 
Allowed regions from the global data at 1σ, 90%, 2σ, 99%, 3σ CL (2 dof) after minimizing with respect to all undisplayed parameters. The results are presented for both 'LEM' (colored regions) and 'LID' (black contours) choices of the NOνA ν_{e}appearance data. The normalization of reactor fluxes is left free and data from shortbaseline reactor experiments are included. The upper (lower) panel corresponds to IO (NO). Note that as atmospheric masssquared splitting we use Δm^{2}_{31} for NO and Δm^{2}_{32} for IO.
