Latest 3-flavor neutrino oscillations results from the NOvA experiment

NOvA is a long-baseline neutrino oscillation experiment. Neutrinos produced by the 850 kW NuMI beam are detected by a Near Detector, located at Fermilab, and a much larger 14 kton Far Detector, located 810 km away. These massive tracking calorimeters are designed to detect and identify muon and electron neutrino interactions with high efficiency. Measuring the electron neutrino and antineutrino appearance rates, as well as the muon neutrino and antineutrino disappearance rates, allows us to constrain the neutrino oscillations parameters. By combining both neutrino data (13.6×10²⁰POT) and antineutrino data (12.5×10²⁰POT), NOvA was able to measure the mixing angle θ₂₃ and the mass splitting Δm²₃₂ with high precision. Ongoing measurements will help NOvA further constrain the neutrino mass ordering and the CP-violating phase δ_CP.
