DESCRIPTION:NOvA is a long-baseline neutrino oscillation experiment search
 ing for electron neutrino appearance and muon neutrino disappearance. To d
 o 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 produ
 ction\, provides a measurement of initial beam energy spectra and flavour 
 composition. The spectra are then extrapolated to a far detector and compa
 red to data to look for oscillations. The experiment is able to constrain 
 several parameters of the PMNS matrix and is sensitive to the neutrino mas
 s hierarchy.\n\nThis seminar presents updated measurements of muon neutrin
 o disappearance and electron neutrino appearance using 10 years of NuMI da
 ta collected by the NOvA far detector corresponding to a 14 ktonne equival
 ent exposure of $26.61 x 10^20$ and $12.50 x 10^20$ protons on target\, in
  neutrino and antineutrino beam modes respectively. The analysis\, present
 ed for the first time in the summer of 2024\, builds on previous results w
 ith improved simulation and roughly double the neutrino beam data.
