Abstract
The NOvA experiment has seen a signal of appearance in a 2 GeV beam at a distance of 810 km. Using protons on target delivered to the Fermilab NuMI neutrino beamline, the experiment recorded 27 candidates with a background of 10.3 and 102 candidates. This new antineutrino data are combined with neutrino data to measure the parameters and in the ranges from (0.53–0.60) and (0.45–0.48) in the normal neutrino mass hierarchy. The data exclude most values near for the inverted mass hierarchy by more than and favor the normal neutrino mass hierarchy by and values in the upper octant by .
