Abstract
We present new ν_µ→νₑ, ν_μ→ν_μ, ν̅_μ→ν̅ₑ, and ν̅_μ→νν̅_μ oscillation measurements by the NOvA experiment, with a 50% increase in neutrino-mode beam exposure over the previously reported results. The additional data, combined with previously published neutrino and antineutrino data, are all analyzed using improved techniques and simulations. A joint fit to the νₑ, ν_μ, ν̅ₑ, and ν̅_μ candidate samples within the 3-flavor neutrino oscillation framework continues to yield a best-fit point in the normal mass ordering and the upper octant of the θ₂₃ mixing angle, with Δm²₃₂ = (2.41±0.07) × 10⁻³ eV² and sin²θ₂₃ = 0.57^(+0.03)_(−0.04). The data disfavor combinations of oscillation parameters that give rise to a large asymmetry in the rates of νe and ν⎯⎯⎯e appearance. This includes values of the CP-violating phase in the vicinity of δ_(CP) = π/2 which are excluded by >3σ for the inverted mass ordering, and values around δ_(CP) = 3π/2 in the normal ordering which are disfavored at 2σ confidence.
