dc.description.abstractWe present updated results from the NOvA experiment for νμ → νμ and νμ → νe oscillations from an exposure of 8.85 × 1020 protons on target, which represents an increase of 46% compared to our previous publication. The results utilize significant improvements in both the simulations and analysis of the data. A joint fit to the data for νμ disappearance and νe appearance gives the best-fit point as normal mass hierarchy, Δm2 32 ¼ 2.44 × 10−3 eV2=c4, sin2 θ23 ¼ 0.56, and δCP ¼ 1.21π. The 68.3% confidence intervals in the normal mass hierarchy are Δm2 32 ∈ ½2.37; 2.52 × 10−3 eV2=c4, sin2 θ23 ∈ ½0.43; 0.51 ∪ ½0.52; 0.60 , and δCP ∈ ½0; 0.12π ∪ ½0.91π; 2π . The inverted mass hierarchy is disfavored at the 95% confidence level for all choices of the other oscillation parameters.pt_BR
