Three-Flavor Neutrino Oscillations at NOvA

NOvA, is a two-detector, long-baseline neutrino oscillation experiment located at Fermilab, Batavia, IL, USA. It is designed primarily to constrain neutrino oscillation parameters such as the atmospheric mass squared splitting, Δ m²₃₂, the mixing angle, θ₂₃, neutrino mass hierachy, and the CP-violating phase, δCP, using ν_μ \ (ν̄_μ) disappearance and νₑ \ (ν̄ₑ) appearance data. NOvA receives a high purity 900 KW instense beam of neutrinos and anti-neutrinos from Fermilab's Neutrinos at Main Injector (NuMI) beamline. NOvA used functionally identical finely granulated liquid scintillation detectors, both situated 14.6 mrad off-axis to the beam direction. The NOvA near detector observes un-oscillated ν_μ \ (ν̄_μ) and beam νₑ \ (ν̄ₑ) events, while the far detector, which is situated 809 km away from the near detector, records un-oscillated ν_μ \ (ν̄_μ) and oscillated νₑ \ (ν̄ₑ) events. We will discuss the neutrino oscillation analysis strategy at NOvA and the latest three-flavor oscillation results from 10 years of NOvA data in this talk.
