This paper reports the first measurement using the NOvA detectors of νμ disappearance in a νμ beam. The analysis uses a 14 kton-equivalent exposure of 2.74×10^20 protons-on-target from the Fermilab NuMI beam. Assuming the normal neutrino mass hierarchy, we measure Δm^2_32=(2.52+0.20−0.18)×10^−3 eV^2 and sin^2θ23 in the range 0.38–0.65, both at the 68% confidence level, with two statistically degenerate best-fit points at sin^2θ23=0.43 and 0.60. Results for the inverted mass hierarchy are also presented.

Abstract

This paper reports the first measurement using the NOvA detectors of νμ disappearance in a νμ beam. The analysis uses a 14 kton-equivalent exposure of 2.74×10^20 protons-on-target from the Fermilab NuMI beam. Assuming the normal neutrino mass hierarchy, we measure Δm^2_32=(2.52+0.20−0.18)×10^−3 eV^2 and sin^2θ23 in the range 0.38–0.65, both at the 68% confidence level, with two statistically degenerate best-fit points at sin^2θ23=0.43 and 0.60. Results for the inverted mass hierarchy are also presented.
