# Analysis 2019

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

Other results is showen by table:

# Analysis 2017

# Second Analysis (2016)

The results of the second analysis were published in 2017. This analysis used an exposure equivalent to from the Fermilab NuMI beam.

## Muon neutino disappearance results

The best fit in the **normal hierarchy** gives:

The best fit in the **inverted hierarchy** gives:

Maximal mixing, where , was disfavored at .

## Electron neutrino appearance results

candidates were observed with a background of .

The hypothesis of inverted mass hierarchy with in the lower octant is disfavored at greater than 93% C.L. for all values of .

## Sterile neutrinos?

# First Analysis (2015)

The results of the first analysis were published in 2016. This analysis used a 14 kton-equivalent exposure of from the Fermilab NuMI beam.

## Muon-neutrino disappearance results

Assuming the **normal hierarchy**, the measurements have a next view:

and in the 68% CL range , with two statistically degenerate best-fit values:

Assuming the **inverted hierarchy**, the measurements have a next view:

and in the 68% CL range , with two statistically degenerate best-fit values:

## Electron neutrino appearance results

NOvA had observed -like events in the FD, with a background prediction of

The range of in the **IH** is disfavored at the 90% C.L. The range of in the **NH** is disfavored at the 90% C.L.
