dc.description.abstract | This Letter reports new results on muon neutrino disappearance from NOvA, using a 14 kton detector equivalent exposure of 6.05 × 1020 protons on target from the NuMI beam at the Fermi National Accelerator Laboratory. The measurement probes the muon-tau symmetry hypothesis that requires maximal θ23 mixing (θ23 ¼ π=4). Assuming the normal mass hierarchy, we find Δm2 32 ¼ ð2.67 0.11Þ × 10−3 eV2 and sin2 θ23 at the two statistically degenerate values 0.404þ0.030 −0.022 and 0.624þ0.022 −0.030 , both at the 68% confidence level. Our data disfavor the maximal mixing scenario with 2.6σ significance. | pt_BR |
