Analysis 2019

The best-fit parameters of neutrino oscillation for each choice of  \theta_{23} octant and hierarchy. The best-fit point is found for the normal hierarchy  \theta_{23} in the upper octant. In this case:

 \Delta m_{32}^2 = +2.48^{=0.11}_{-0.06} \times 10^{-3} eV^2/c^4

 sin^2 \theta_{23} = 0.56^{+0.04}_{-0.03}

 \delta_{CP} = 0.0^{+1.3}_{-0.4} \pi

Other results is showen by table:

  NO, LO IH, UO IH, LO
 \Delta m_{32}^2/ (10^{-3} eV^2/c^4)  +2.47  -2.54  -2.53
 sin^2 \theta_{23}  0.48  0.56  0.47
 \delta_{CP}  1.9  1.5  1.4
   +1.6\sigma  +1.8\sigma  +2.0\sigma

Second Analysis

Nue appearance results (Preliminary)

Numu disappearance results (Preliminary)

Best fit in Normal Hierarchy

 |\Delta m_{32}^2 | = (2.67 \pm 0.12 ) \times 10^{-3} eV^2

 sin^2 \theta_{23} = 0.40^{+0.03}_{-0.02} (0.63^{+0.02}_{-0.03})

Best fit in Inverted Hierarchy

 |\Delta m_{32}^2 | = (-2.71 \pm 0.12 ) \times 10^{-3} eV^2

 sin^2 \theta_{23} = 0.40^{+0.03}_{-0.02} (0.62^{+0.02}_{-0.03})

Maximal mixing excluded at  2.5 \sigma
