NOvA is a long-baseline neutrino oscillation experiment searching for electron neutrino appearance and muon neutrino disappearance. To do this, NOvA uses the NuMI beam at Fermi National Accelerator Laboratory along with two functionally identical detectors, separated by a baseline of 809 km. A near detector, which is close to the point of neutrino production, provides a measurement of initial beam energy spectra and flavour composition. The spectra are then extrapolated to a far detector and compared to data to look for oscillations. The experiment is able to constrain several parameters of the PMNS matrix and is sensitive to the neutrino mass hierarchy.

This seminar presents updated measurements of muon neutrino disappearance and electron neutrino appearance using 10 years of NuMI data collected by the NOvA far detector corresponding to a 14 ktonne equivalent exposure of $26.61×10^{20$ and $12.50×10}20$ protons on target, in neutrino and antineutrino beam modes respectively. The analysis, presented for the first time in the summer of 2024, builds on previous results with improved simulation and roughly double the neutrino beam data.
