The NOvA experiment has seen a 4.4σ signal of e appearance in a 2 GeVμ beam at a distance of 810 km. Using 12.33×1020 protons on target delivered to the Fermilab NuMI neutrino beamline, the experiment recorded 27 μe candidates with a background of 10.3 and 102μμ candidates. This new antineutrino data are combined with neutrino data to measure the parameters |Δm 2 32 | = 2.48 +0.11 -0.06 x 10 -3 eV2 / c4 and sin2 θ23 in the ranges …
