Threeflavor oscillation parameters from our fit to global data as of November 2017. 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. 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). 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. 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 (right) and its δ_{CP}independent modulus (left). The red (blue) curves are for Normal (Inverted) Ordering. 
CPviolation: unitarity triangle
pdf jpg 
Leptonic unitarity triangle for the first and third columns of the mixing matrix. 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 contours for Normal (right) and Inverted (left) ordering are defined with respect to the common global minimum. 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 (full regions with best fit marked by black star) and AGSS09 model (dashed void 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°. Right: Δχ^{2} dependence on Δm^{2}_{21} for the same three analysis after marginalizing over θ_{12}. 
Synergies: atmospheric masssquared splitting
pdf jpg 
Determination of Δm^{2}_{3ℓ} at 1σ and 2σ (2 dof), where ℓ = 1 for NO (upper panels) and ℓ = 2 for IO (lower panels). The left panels show regions in the (sin^{2}θ_{23}, Δm^{2}_{3ℓ}) plane using both appearance and disappearance data from MINOS (green), NOνA (cyan) and T2K (red), as well as DeepCore atmospheric data (orange) and a combination of them (colored regions). Here a prior on θ_{13} is included to account for reactor bounds. The right panels show regions in the (sin^{2}θ_{13}, Δm^{2}_{3ℓ}) plane using data from DayaBay (black), reactor data without DayaBay (violet), and their combination (colored regions). In all panels solar and KamLAND data are included to constrain Δm^{2}_{21} and θ_{12}. Contours are defined with respect to the global minimum of the two orderings. 
Synergies: determination of Δm^{2}_{3ℓ}
pdf jpg 
Bounds on Δm^{2}_{3ℓ} from reactor experiments (black) as well as Minos (green), NOνA (cyan), T2K (red) and all LBL data (blue). Left (right) panels are for IO (NO); for each experiment Δχ^{2} is defined with respect to the global minimum of the two orderings. The upper panels show the 1dimensional Δχ^{2} from LBL accelerator experiments after imposing a prior on θ_{13} to account for reactor bounds. The lower panels show the corresponding determination when the full information of LBL and reactor experiments is used in the combination.

Allowed regions from the global data at 1σ, 90%, 2σ, 99%, 3σ CL (2 dof) after minimizing with respect to all undisplayed parameters. 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.
