First neutrino oscillation measurements in NOvA

The NOvA experiment uses the Fermilab NuMI neutrino beam and a newly constructed 14 kt detector to address several open questions in neutrino oscillations including the neutrino mass hierarchy, the precise value of the angle θ23θ23, and the CP-violating phase δCPδCP. The experiment has been running since 2014 and has recently released its first results from an equivalent exposure of 2.74×10202.74×1020 protons-on-target equal to 8% of the eventual data set. Measurements of νμ→νμνμ→νμ oscillations find Δm322=(2.52−0.18+0.20)×10−3 eV2 and 0.38
