Title: First neutrino oscillation measurements in NOvA

Abstract

In this study, 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 θ23, and the CP-violating phase δCP. The experiment has been running since 2014 and has recently released its first results from an equivalent exposure of 2.74 × 1020 protons-on-target equal to 8% of the eventual data set. Measurements of νμ → νμ oscillations find Δm232 = (2.52+0.2–0.18) × 10-3 eV2 and 0.38 < sin2θ23 < 0.65 for the normal neutrino mass hierarchy. The experiment has observed νμ → νe oscillations at 3.3 σ C.L. in this early data and disfavors the inverted neutrino mass hierarchy in the range 0.1π < δCP < 0.5π at the 90% C.L.
