Latest Three Flavor Neutrino Oscillation Results from the NOvA Experiment.

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 instense beam of neutrinos and anti-neutrinos from Fermilab's Neutrinos at Main Injector (NuMI) beamline. The NOvA near detector (ND) observes un-oscillated ν_μ \ (ν̄_μ) and beam νₑ \ (ν̄ₑ) events, while the far detector (FD), which is situated 810 km away from the near detector, records un-oscillated ν_μ \ (ν̄_μ) and oscillated νₑ \ (ν̄ₑ) events. The best fit values of the oscillation parameters are extracted by performing a joint fit of the far detector predicted events to data from ν_μ → ν_μ, ν̄_μ → ν̄_μ, ν_μ → νₑ, and ν̄_μ → ν̄ₑ oscillation channels. We present latest joint fit results from NOvA based on a neutrino-beam exposure of 27.24 × 10²⁰ POT and an anti-neutrino beam exposure of 12.55× 10²⁰ POT and improved simulations.
